The Problem With These Headlights

Different Types of Headlights Explained
Headlights play a significant role in shaping a car's overall appearance and personality. Their design can contribute to the vehicle's aesthetic appeal and help define its unique character, making them a crucial aspect of automotive design and styling.
Headlights today are undergoing some of the biggest technological changes seen in the history of the automobile, from Carbide Lamps used in the early days of cars to laser lights of the modern era.
The earliest headlights were found in the late 1880s, fuelled by Acetylene Gas or Oil. Back when cars were in their infancy, headlights were flames, burning behind glass lenses and fed with acetylene gas. they were quite similar to the gas lamps used in homes during that time.
The first electric headlight was introduced in the year 1898 by the Electric Vehicle Company and in 1904 American automaker Peerless was the first manufacturer to introduce electric headlights across its range. Four years later, British-based supplier Pockley Automobile Electric Lighting offered a complete set of electric lights including headlights, tail lights, and sidelights, which were powered by an eight-volt electric battery.
When you picture old, classic cars, you probably imagine cars with sealed beam headlights. By 1939, sealed beam lights had been introduced, and became compulsory on all vehicles in the US between 1940 and 1983. They used a parabolic reflector, as well as a lens and a filament sealed together, to offer a brighter, more focused light.
In the earlier 60s halogen headlights instantly became the standard tech in Europe. In 1962, a French, German, and Italian consortium of bulb- and headlamp-makers produced the first vehicle-mounted halogen lamps.
These provided brighter, more durable headlights due to the way the halogen gas reacted with the tungsten. This process gave drivers much higher road visibility, particularly on high beam settings.

13:10 tell that to all the idiots that put LEDs in their old car lights thinking it’s better, blinding everyone while having a worse light.

[@user-kx7iz6qk6b]

You need adjust the lights after you put them in, that's why it blinds people.

[@jjjacer]

this was also an issue with HID's as people would get kits to run them in the older reflective halogen housings, basically LEDs and HIDs should only be run in projector housings that shape the beam, although i do have LEDs on my van which used sealed beams, but the LED housings do have cutoffs so they dont blind drivers more than normal (sadly high profile vehicles will always blind cars just do to their height) but i dont really drive that van at night so its less of an issue. although there are supposed to be LEDs with the proper filament pattern that can work in reflector housings, i still wouldnt recommend them, My biggest complaint is i do a lot of bad weather driving so the whiter LED's/HID's cause a bit to much back scatter from rain/snow, sorta wish more of the newer lights came in the lower kelvin color temps

[@LarryNgetich]

I bought 7 inch round LED headlamps for my old Prado from Aliexpress and it's so much better driving with them, especially when it gets foggy. No regrets.

[@jre617]

@@jjjacer As I understand it, you can get a way with HID bulbs in standard halogen housings because the 'bulb' emits light similarly to the halogen bulb. But LEDs do not emit light with the same 360 degree pattern as HID or halogen bulbs and so you end up less effective light patterns.

[@Mobitz2.3-4]

@@user-kx7iz6qk6b Because of the LED design it's impossible to get the beam specific enough. they're much better now than before but they still create to much glare because they are being used in a housing designed and made for a different technology. I desperately want replacement LEDs to work because I have H11b's and they really are bad. I tried top tier LEDs and they created too much glare. Adjusted them, but the sharp cut off just isn't there!

[@nroose]

Recently headlights have gotten much brighter. That's great out in the wilderness. And pretty bad in the city. People drive around my city without their lights on and don't notice. That's unsafe too. But very bright headlights make it hard for everyone to see. We need a city lights setting that is more for the purpose of helping people see the cars with the headlights on, but don't have to illuminate everything in front of them.

[@etmax1]

That is compounded by that addition of day time running lights that lack proper directionality and sometimes approach the intensity of some headlights. Daytime running lights should be off when headlights are on unless they are either directed down and/or are significantly less bright.

[@H-LectorSA]

There is, it's the Daytime lights

[@dufonrafal]

It's not about brightness but control, low beams are design to throw light below drivers eyes. They need to be properly adjusted and you need to use bulbes design for them. Putting LED in an halogen headlight will cause the light to go all over the place and blind other road users.

[@chefchaudard3580]

About the LEDs : in cars and home lights, the semiconductor produce a blue light. It goes through a phosphorus coating that actually glows white.

[@crabjoe]

You know what I miss about headlights? It's the glass lens! Never had to worry about yellowing, when they were glass!

[@paulqueripel3493]

That's the first time I've heard a halogen as being inert. Wrong group in the periodic table.

[@neurofiedyamato8763]

The fact it reacts to Tungsten to prolong it's life means it's not inert/noble lol

[@electronicallyscannedarray]

[@jimbroen]

Another advantage of sealed beam was that they were standardized. You could go into a Walmart and buy an inexpensive standard size seam beam light which would fit in any car.

[@dr.burtgummerfan439]

Remember when you could walk into the parts store and say "I need a headlight" and the only question was "Round or rectangle?"😂

[@berndkahlau9770]

I love the Matrix LED Lights in my ID.3. Turn off automatically within city limits, turn on above 60 km/h and so far in the last 10 months I was never blinkt at from oncoming traffic while on high beam light or any funny reactions from people driving in front of me 👍 Nicely done video 😊 Cheers from Germany 🇩🇪

[@crabjoe]

I've got Matrix headlights on my BMW. I love them, but I don't think people driving in front of me like them. I say this because I've had people pull off to the shoulder to let me pass. I feel the reason is because as parts of the light beam turns on and off and moves around, it confuses them. Possibly making them think I'm flashing my high beams. It gets really bad when I have oncoming traffic. Because when there's no oncoming traffic, my high beam shoots to the left and right of the car in front of me. When a car comes up, the left side high will either drip down or turn off, then it's back on.. making the car in front think I've flashed my high beams.

[@manoman0]

@@crabjoe They are confusing. The light moves around giving a wrong impression of what's truly happening at night on a road.

[@mikldude9376]

I am old ish😊 , I’ve driven with all of those lights except for the old old chemical gas ones in the early 1900’s. Good lights are important , but unfortunately they are often misused in the wrong application, and also sadly , they are often used by uncaring ignorant drivers . I might add , as someone that worked in car repair industry , and also drove trucks for a living for years , headlights in many countries are probably one of the most poorly policed safety items on a motor vehicle , that goes for general specifications and also design, like for example uniform headlight heights , if you have been in normal sedan sitting at the traffic lights and had higher SUV or four wheel drive sit behind you with the much higher headlights shooting through your back window lighting up the inside of your car like a bright sunny day , you know what I mean. Poorly adjusted headlights, incorrect globes and lights fitted to unsuitable headlights with the wrong reflector shape . Bright lights are fine if they are adjusted and set up correctly. I’d say if you drive highway there is a happy medium to the brightness of lights , even if you are alone on the highway and driving for hours at night , having lights that are so powerful when they hit the shiny metal back of a metal road sign and reflect back at you can really make your eyes sore. A good spread of light that is fairly white but not so white it hurts to look at is good . And low beam lights that are still nice and bright , but adjusted away from oncoming drivers and below their windscreen level . Some cars have height adjustable lights from a dial in the cabin which Is pretty cool , other have dampened height self adjusting mechanisms. Then there are the old cars that are just set at the factory, they have a device they stick in front of the headlights which shows where the main part of the beam is and adjust it to the centre line while on high beams . Of course when you put something heavy in the boot/trunk , the back of the car goes down pointing the old style headlights up a bit , you get that in the pick ups too. I remember as a young bloke driving up the country at night on a very windy mountain road I was going around a bend at a fair rate of speed , there was a very big drop down into the valley on my side of the road , and some asshole came around the bend with headlights and two powerful sets of driving lights on full beam , I was absolutely blinded for about 4 or 5 seconds , I had pretty good nerves back then , I held the steering wheel in same position and managed to negotiate the bend , the asshole just continued on with out dipping his lights . Humans can be ass holes sometimes . I must confess , I probably like leds the best because they light up instantly, they don’t need a few seconds to warm up. Although my current lights in my car are HID with the correct reflector on low beam and the original old halogen globes for the seperate high beam lights , which I have to say are just adequate , however they are very comfortable for driving for hours at night . Here is another little bit of trivia , blue is the hardest color of the light spectrum to see and look at , if you look at the dash lights of many modern cars they are a pretty blue , and people always like the pretty blue and no doubt that is why most car makers use it , but the fact is , blue is actually sub optimal, the best color for long distance night driving that is easier on the eyes is actually red. As an old truck driver at one stage I did a fatigue management course , and this one of the topics mentioned for long distance driving. And having driven many many big rigs over the years , I can confirm red hurts the eyes less.

[@musicnstuff2910]

Can someone add a TLDR?

[@lawnmowerdude]

I also hate it when my water in cold weather could get freeze.

[@wday8302]

I drove at night more than a few times, Company Vehicle had a "Light Bar"!, A very Expensive Light Bar, It only made the area brighter that the Low Beam covered, Making the LED pointless at Highway speeds

[@R4M_Tommy]

A light bar is made for driving offroad, at crawl speeds. Don't be the moron who has it on while on public roads, in traffic.

[@bofty]

Whoever fitted it didn’t calibrate it right, take it somewhere and get it fixed

[@NatesHomeTours]

I've added a $30 single row 22" light bar to my Jeep Cherokee that comes on automatically with when I turn the brights on, I can see much farther down the road. Whoever put yours on didn't do it right or they got a flood instead of a spot beam pattern. Mine is a cross between flood and spot. The outer lights are flood which really light up the sides of the road way better. The center ones are spot and shine light way farther down the road than using just the high beam of the HID lights. (mine use the shutter style). All that with the light bar mounted below the front license plate. If it was mounted higher I would get even more performance out of it.

[@Real_Jcan]

It depends on what that light bar was designed for. Some is just to light right ahead of you for off-roading ie camping at night. Off road lights design for speeding in rally or so have a further throw

Also leds do wear over time so the light output is getting lesser when they get older. Replacing them will be very expensive.

[@drewwyatt1274]

Headlights that follow the turning of the steering wheel were available on 1967 onwards Citroen DS models, with up to 80 degrees of arc. I believe they were cable operated.

[@starlightiris]

The thing is, it’s really not that hard to make warm white LED headlights. I don’t understand why this is so rare!

[@musicnstuff2910]

Oh Yh, that’s true!

[@rps215]

I am guessing because cold white light is better for visibility, just like how they replace the older warm white LP and HP Sodium Vapor street lights with cold white LEDs.

[@davinp]

The main problem with LED headlights is that are too bright on some cars and can blind you. For example, if you driving a sedan and there is a big truck behind you, it's headlights will shine in your car. Also, if the LED light malfuctions, you cannot just replace the bulb as it is not a regular bulb like halgeon are. Instead, you have to replace the entire headlight assembly. This is true on the 2014 and newer Toyota Corolla.

[@knightwolf200612]

There are countless H4 and H7 replacement lights for halogen to LED. Most are just as easy to replace as the original halogen. So you can't blame that on LED, blame it on the car designers.

[@travis3810]

ever heard of matrix LED?

[@abyjose9772]

Well explained. Appreciate your effort.

[@christopheckstein8683]

Pretty nice historical summary. It should be mentioned that it's not only about brightness, intensity, or color temperature. Modern headlamps need to have a good contrast (ratio of intensity between areas where they would potentially glare others and where high intensity is needed for visibility). A lot of people here confuse bright headlights with dazzling ones. Regulations allow a lot of flexibility here and there are bad examples even on new cars. Watch out for a good IIHS headlamp rating in the US market. Manufacturers can only achieve a good rating in this test when both range and low glare risk is achieved. Glaring headlamps are often adjusted wrong or modified by people who don't know what they're doing or if manufacturers are trying to save money. Technically Laser and LED headlights are most suitable to design high performance headlights which achieve great visibility and low glare. Sophisticated optical concepts and adaptive headlamp systems take this to the next level.

[@TheRealKhaya]

Absolutely informative 👍👍 I love the LED lights and Adaptive LED lights. Adaptive Laser lights 🔥

[@adewouters]

Interesting stuff, thanks for the video. As many other comments suggested, I'm also sensible to oncoming lights at night and it is indeed quite annoying. This is why I think the best is matrix LEDs, provided the matrix part is actually working well.

[@flatheadV8]

Best headlights I have had were on my 1954 Sunbeam Talbot 90. Lucas, yes Lucas P700, 7 inch. I sold the car two years ago so I can assure you that I prefer them to the LED lights on my daily driver.

[@xenvector]

How did I end up watyching this at 4am even tho I have to wake up at 8 this morning?

[@calebdanielherman4913]

The issue is that Xenon Laser and LED are far too bright for oncoming traffic. You're more likely to blind the other person driving towards you, which is always a bad idea. There is zero reason for them to be in every brand new car on the road.

[@musicnstuff2910]

Mmm, I like them, you just gotta make sure you turn them down or smth

[@mauritsvw]

As far as I know, on low beam any type of headlight technology should not blind oncoming traffic if adjusted properly. That amounts to the beam being cut off before it reaches the oncoming driver. As far as high beams go, the onus is on the driver to cut to low before oncoming traffic can be blinded.

[@NatesHomeTours]

The one innovation that all truck makers need to implement would be auto adjusting lights. So when you attach a trailer, it measures the amount of squat and adjusts the headlights down accordingly, so as not to be blinding. When the front of the truck is angled up due to squat, it changes the angle of the cutoff line and the headlight becomes blinding.

[@Colstah]

I'm getting to the point where I contemplate fitting LED spotlights so I can blind the drivers of the oncoming cars that have their LED's on high, or adjusted poorly, and blind me. And don't get me started on auto shops selling non-ADR compliant lamps meant for off-road use.....

[@a.m.9357]

Good video. Just want to say these days headlights are just too powerful and have in fact become a danger to drivers. There is no need for "laser headlights" in my opinion. Car manufacturers have now become light polluters. Instead of making quality cars, they are using cheap childish LED lightings to entice buyers. And the biggest offenders are Audi and Merc.

[@Scotford_Maconochie]

My car came with adaptive HID projectors (aka xenon) as standard equipment. I then decided to upgrade to LED using a fully plug and play LED and compared them driving on a rural road in total darkness and both performer extremely well thus using the high beam almost optional since the low beam even have excellent range. Needless to say its an aftermarket kit so I always keep a pair on xenon bulbs in the glove box.

fun fact it was the Audi R8 LMX that first came with laser lights on a car not the BMW I8

[@adityagauba630]

One of the main reasons for blinding LEDs is retrofitting them aftermarket on halogen bulb reflector assembly.. which uses mirrors to project light on the road. Which is meant for halogen bulbs of a same filament shape and light colour temperature. But retrofitting LED in this assembly is the reason the light spreads to peoples eyes..

[@talos86]

You can put Osram and Philips LED into any headlights. They have Retrofit lineup for non projector H* type lights. In the EU there are a few countries(like Germany and Austria), where you can use their LED produtcs and you get the TUV licence trough the manufacturing company(the process is in the user manual). You dont have to adjust anything, the Retrofit LED "bulbs" working as the original halogen ones out of box.

[@cosmicgreen]

Good sum up.

[@idkwuisp7626]

Whatever technology the headlight uses, doesn't matter. All headlights are properly aligned from the factory. The problem is when people mess with the height adjustments, not knowing what they are doing, or they put LED bulbs in housings that are not designed for LEDs. Aiming the headlights can be a PITA, which is probably why there are so many cars with headlights pointing at the sky.

[@bobyoung1698]

I'd be happy with a good set of LEDs. Also, it would be great if pickup trucks (especially those with lift kits) and SUVs would be required to lower the height of their headlights.

[@briang70]

I just traded in my 2008 Mazda 3 S Sport (with smoke tinted lenses) for a 2017 Passat w/ Tech. The stock headlights on the Mazda always seemed lacking. I also have an '07 Tacoma 4X4 with stock halogens. The Taco's lights are so bright, I rarely use the high beams. With the VW's LED lights, I feel sorry for oncoming traffic. I never need the high beams on the VW.

[@Oo-IIII-oO]

Bring back the sealed beam. Does teh job well, never fades, affordable and easy to replace. Some of these headlights can total a car out. We're talking thousands of $ for a stinking headlight. Totally un necessary. Recently a buddy's Rover DRL went out. Can't replace just a bulb. $3500 for a headlight because the DRL or the signal lamp is out. Insane

[@angrypenguin956]

I've driven cars with most of those technologies, but the oldest with the chemical system. Things have improved tremendously, and it's for the better. The problem with newer technologies is when you try to retrofit them in old applications. Xenon and LED systems are fine when they are designed for that specific purpose from the ground up. In some instances, you can use LED bulbs in older cars with decent results, but some things must be kept in mind. First, you need high-quality LED bulbs or sealed beams (They are not cheap) and must also align your headlight properly. Sometimes, even that won't work.

[@mauritsvw]

Of course the new technology provides the best results, but I foresee maintenance problems with such complicated technology when the vehicle gets older.

[@robbiewu60]

The problem isn't the headlights per se, it is how good quality hid and led are only available on expensive cars. There is also this misconception that 6500k being the "daylight" color ia the best option for visibility. Based on trial and error I find the 4000k range to offer the best balance between visibility and comfort to the eyes, the 6500k scatters too much in rain and wet surfaces simply absorb it.

At 13:20 you stated that it is impossible to retrofit LED bulbs to older headlight assemblies. That is not correct. There are manufacturers making LED retrofit bulbs with small lenses over the LED array that mimic a traditional halogen H4 bulb. Using a light meter on a 6” grid at 100 feet I was able to match the beam pattern within 5%, LED vs halogen. It did require some adjustment of the reflector but nothing I couldn’t do with a screwdriver. It does require some time, about an hour, but in 5 years I’ve never had anyone flash their lights and everyone I ask says that they are fine.

[@manoman0]

Early Lights= Be seen Modern lights= actually SEE!

[@lazydadsgarage]

Hid in a projector was the best of all worlds as long is it's properly aimed. If you think new led lights are the problem you've never had a newer base 4x4 F250 or F350 with halogens pull up behind you

[@midas7934]

Wow, so headlight fluid was a real thing back in the day🤣

[@arturseversons3444]

I don't know which type each car uses, but the lights on any modern car are an absolute menace to the oncoming traffic. Or even a car in front (rear view mirror). Hate them. I have halogen lights on my car and I drive around happily knowing that I'm not blinding anyone 😇

[@diyi75]

Figured it would be a lot of b***hing on here, about bright LED\HID lighting on the road😂

[@Phil-D83]

Hid and led (no experience with laser leds) really helped. They can blind people, but let you see at night

[@hankhillsnrrwurethra]

People are like freaking deer. Just don't look directly at oncoming lights.

[@calebdanielherman4913]

Except oncoming traffic. They can't see at all. Hid and LED are too dangerous to be headlights.

[@psychoal1967]

Two issues with the later ultra bright headlamps. 1. They still blind on coming drivers when the vehicle they are fitted to hits a bump or goes over a crest in the road. 2. if you need headlamps that bright you are either going too fast / need your eyes testing / need to take your sunglasses off!

[@NatesHomeTours]

Or you want the headlights to shine farther down road and into the ditches, so you can see the deer that like to come out at night sooner and not hit them, so you don't destroy your vehicle. The farther down the road you can see the deer the better chance you have of braking and not hitting them.

We've come a long way!!

The real problem with LED is the high blue light content. This blue light is not much of a problem in normal conditions...It's a huge problem in wet conditions. The blue light scatters easily off water particles or even dirt/salt on the windshield. This creates a glare. GLARE IS REAL but very difficult to measure. There are highway driving videos that show LED streetlighting and HPS side by side done in the rain. You'll see under HPS, the orange light cuts right thru the rain and wet surface to provide decent visibility...The Blue LED light scatters, and everything appears very dark because too much stray light is entering the eye. The LED lighting gives a false confidence of visibility when glare produces significant gaps in visibility. Additionally, old people are far more affected by blue light glare than young people. The cornea yellows with age and blue light scatters passing thru the yellow lens, making everything in the field of view appear darker as a result. That's why old people HATE cars that use white headlights and young people don't really understand why. The young people generally think those old people just don't like the new white color or are exaggerating the glare. I'm a lighting engineer...I could go into the details of Rayleigh scattering, veiling luminance, and disability glare from cold white light - the effects on visibility especially for the elderly, and especially during inclement conditions (rain, fog or snow)...But the bottom line is that all street lighting and headlights should be warm white 3000K CCT max, though I'd push for warmer 2700K.

[@jimmygmc6917]

they need to put automatic dimmers on the new headlights the people who have them do not dim their high beams to oncoming traffic at night....

[@TomPauls007]

I'm a bit confused. ALL of these lights are "electric!" Why is the '57 chevy only labelled "electric?" I think it is "incandescent."

[@Rsonny]

Brb gotta refill my headlight fluid

[@GunsmithSid]

Suprised to hear that LED lamps can project light up to 300 meters! 🤦‍♂️ 12:10

[@remissiveslave]

Hate being blinded by these new lights they use these days.

[@knightwolf200612]

The evolvement of headlights is just stunning. I recently put H4 LED in my old 1997 car with reflector headlights. kzbin.info/www/bejne/bHncpKN8o8ychZo It needed new headlight units because the reflector got dull, so with a brand new clear reflector I wanted to try LED. There are a lot of H4 and H7 LED types from countless brands, but most are not good. When research well, you can find models that actually produce halogen-style light pattern without scattering/blinding. So you really can't just say it's not gonna work, because it does work! The most important is to have the actual LED's in exactly the same location as a halogen filament. Only 1 mm up or down ruins the light pattern. But there are manufacturers who does that really well and it works great without blinding anybody. And again, clear glass and reflector as a true mirror is mandatory. And ofcourse height-adjustments doing right!

[@petrussoeganda109]

8:15 the best lamp 4.600 ~ 4.800 K

[@user-wy9gd8nv6m]

Bro please make video on mahindra engines ❤❤

*Mahindra? Seriously?*

[@SiiliViin]

I have no experience with laser headlights, but all other types, Xenon is still king and best. And I am talking about how much light it output. Bi-Xenon is rubbish, but use xenon with proper dedicated lamp and it is really-really good.

[@rolandraijmakers]

My BMW 320i from 2013 had bi-xenon, and that was impressive. But my 2019 BMW 320i with laser light is just twice as good as Bi xenon. Especially the beam assistant which changes the beams to oncoming traffic and traffic in front. I can drive in most cases continuously with the high beams on.

NEW FOR 2476 KIA FORTE:Atom Blast tube lighting system (Creates a small nuclear Explosion on the front of your car)

[@TheAussief1]

Got to laugh at 300m, just setup with a set of driving light is seeing the white line on the road going up a hill from 700m to kilometre away. And it’s “only” halogen. Abet 24v 125w globes.

[@superhuber]

Everything is fine, but it has gone in a very bad direction where car headlights now cost more than the whole car used to cost.

[@Psycandy]

yes new headlights mounted higher up blind everyone, except in France. Compare accident and mortality rates

[@wildthing6668813]

Give me an Halogen headlight any day the bulbs could be replaced but more modern vehicles with LED lights mean if one diode goes you need a new light and indicator as these are sealed units.

[@katieandkevinsears7724]

The problem with the new headlights is blinding oncoming drivers. I'll stick with halogen as long as I can.

[@neilbmarquez211]

Amazing.

[@rachids3030]

We are in the last light invention ever on car. What is better then LED's?
