It was not until the 90s that the Halogen bulbs took over. They did take over fast because of styling because the glass sealed lights basically came in two shapes, round and rectangle. With Halogen, you could get very creative with the shape and contour of the plastic headlight assembly.

@@luketorpedo It does say and show in the video that it's being spread by a lens. Not sure why they're using a LASER to start with, maybe it produces more uniform light to help lessen light scatter?

[@jasexavier]

​@@argh1989 A laser can produce the smallest point source of any light source. The smaller the source, the easier it is to focus and change the shape of the light with optics. Laser lights can achieve better focus than even short-arc lamps. In contrast, LEDs are fairly large sources, and quite difficult to focus, especially to create low beam patterns. In addition to the phosphor, there will also be a filter that blocks the wavelength of the laser, so there's no chance of any coherent light shining through. As far as the final color, this just depends on the phosphor, so you could have 3500K or 4000K laser lamps.

[@YannR34]

You don't have a laser beams going out, the beam is to create the reaction with phosphor. It's to creates more light with less energy. The laser beam do not leave the head light.

[@Henchman_Holding_Wrench]

While the tech is impressive, what I miss about 90s headlights is that I never had white and blue spots seared into my eyeballs by oncoming traffic because we were stationary at a red light. Bonus round, my neighbor across the street likes to leave his car on in his declined driveway for up to an hour. Just completely oblivious to his white LED headlights beaming into 3 houses.

[@danhardhat2]

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.

[@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

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.

[@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.

with halogen it's pretty similar, the housing may vary from car to car, but the bulbs have standardized system like H4 or H7. That way we can even carry some spares in the car without sacrificing much space and when one burns out, it could be changed out on the side of the road

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.

[@upon1772]

Totally agree. I tried putting 6000k LED bulbs in my car, and it felt outright dangerous to drive at night in the rain. Switched to 4200k bulbs and some 2700k fog lights and it is a HUGE difference. Bigger number isn't always better...

[@dickmelsonlupot7697]

4000K to 4500K is the best since it's *WARM WHITE* Anything beyond that is just being obnoxious. 2500K is also good but mainly for fog lamps or aux lamps/lights that you need when going off road or if you plan adding more lights to make you more visible when it rains, snows or when it gets foggy.

[@thebrowns5337]

Finding any 6000+ kelvin clour temp LED that can accurately render colour isn't going to happen. 4500k to 5000k has the best CRI and would therefore make better headlight bulbs for city driving especially. They choose 6500k as it projects further due to there being less yellow coating on the chip.

[@igorzgardan5639]

Conversion kits exist for both Halogen and Xenon lights. I've hada car with both halogen and xenon light bulbs which i upgraded both to LED and here's what ive noticed. The number one thing that people complain about is how LED blind other drivers. I found that to be the case when installing them on my halogen lights as the mirrors do scatter the light more than lenses in xenon lights. My lights were a bit dirty, and not just dirt but the plastic being faded and scattering the light even more. After cleaning the headlights, ive noticed another thing on the halogen mirror lights: the direction they were facing. Most people don't even bother to do this, but alignment of headlights is crucial for both you having good visibility and not blinding others. Mine were extremely high up, basically hitting most people's windshields + i didn't have the best visibility either. After fixing the two major factors. My halogen mirror lights had not only a distinct cut off line, but were also not blinding others. In xenons lens lights it's pretty much the same thing especially with headlight alignment except the cut off line is way more distinct as lens lights don't scatter light as much

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.

I haven't hit that section yet, but if they mean 'Not enough to heat the headlight cover and get the ice to melt off', THAT could be true. The LED lights don't HAVE to put out tons of heat, though. Under-volt them slightly (for ones that don't have on-board power drivers, anyway) and they lose a little light but drop a LOT of heat output. They don't put a lot of heat into the headlight assembly, though, at least not when compared to incandescent bulbs! And for the one reply, actually wires DO put out heat, it just is normally not enough to need to care about IN COMMON USE. Try an experiment...but CAREFULLY, because I already know this answer. Use a normal headlight bulb, and feed it through 5-10' of 14 gauge copper wire. Wad/fold/roll that copper wire up and put it between two dish cloths. Let it run for a few minutes, but keep an eye on it because if your wire is sneakily-cheap (copper-clad aluminum or the like) it may heat up a LOT. Even pure copper will warm that up, though, if your headlight bulb takes up a few amps of power. In normal open air it may not get hot enough to be an ISSUE, but it still gets hot even for 12v at 5-7A, even in 14 Gauge braided copper wire. Wires get hot...humans usually just have 'crappy sensors' available with which to notice that. If you don't insulate the wire, it usually just soaks the heat out into the ambient air and we don't notice anything, but they DO get hot unless you're wildly-oversizing the wires. Normal wires expect that you will be allowing them some variety of heat sinking into the air/the car's frame/whatever.

​@@rps215 The white LEDs were chosen simply because they were energy efficient and you know, because of the whole "save the planet" bullshhttt. Lots of modern street lights that are LED actually use warm white LEDs now or at least ones that lie between 4000K to 4500K or even 5000K since people and manufacturers have found that super bright white is bad for everyone's eyes.

[@thebrowns5337]

​@@rps215 cold (6500k) colour isn't better per se. Those LEDs project further as there is less colour coating on the chip, but for colour rendition (therefore better subject identification and therefore better shadow really so better depth perception) 4500k is far better. In all hosety 4500 or 5000k would be better for drivers and other road users. But as projectikn is slightly less it doesn't market as well and it doesn't give that fresh look that makes the car look newer or higher spec than a halogen version... so we get the crappy 6500k versions.

I have been driving for 50+ years and owned cars of late 50s vintage to 2023. The absolute BEST headlamps I ever experienced were round, single lens, non-sealed, dual beam, with euro-sourced 50W/100W halogen bulbs. The lens crystal pattern was so well designed that the low beam could be aimed so as to cut off just below the rear window glass of a car approx 4-5 car lengths in front and the high beam pattern allowed aiming down the road with very high precision.

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.

A properly designed aftermarket halogen light unit from a company like Cibie or Marchal or even Bosch gave you a round or rectangular light that replaced the original sealed beams of the era and had a light output that actually let you drive comfortably and safely at night. Replacing the standard 55/65w bulb with a 75/100w Osram bulb would give you a low beam that increased your seeing distance without being obnoxious to an incoming driver while giving a high beam equivalent to a rally drivers.

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.

There should be legislation to get rid of these painful blue headlights. They need to taken out of production, and cars with such existing headlights should be mandated to be retro-fitted with proper headlights. Though I am in my 70's I find that even young people complain, many claiming they will no longer drive at night. I believe that millions of people find driving at night almost unbearable. It is not merely a case of some drivers not using their low-beams. Low beams will shine into the eyes of oncomers when cresting even the slightest hill. I find myself blinking at blue headlights that were already on low beam, even on flat ground. . I am happy to hear about "matrix" type lights. I have often thought that a cluster of very narrow light-beams that can be selectively turned off is the solution, though quite expensive, and could take many years to produce enough variations to retrofit the millions of annoying blue lights that already exist. Such a "lazer" cluster should contain way more than the dozen or so individual lights, perhaps about 100. This way these large [usually yellow] traffic signs with their much too retro- reflective lettering won't wash out the visibility of everything else around them. I believe it is time for national legislation to address the safety concerns these new blue lights are causing. Even if it causes their manufacturers considerable monetary pain, they should never have been produced in the first place. Time for a forum on Facebook, perhaps ?

I think HIDs are better than LEDs and the other newer ones. With my Lincoln MKZ I'm glad I went with standard adaptive HIDs instead of the LED option. If an LED fails you can't simply replace the individual bad diode, the whole headlight assembly needs replacing (up to $1,000+ for an MKZ). It's a lot cheaper to replace a $150 HID bulb.

I love LED headlights, however manufacturers need to reconsider making every light as bright as possible, and aftermarket LED headlights need to be heavily regulated. The cheap ones you get on Amazon have no beam pattern and scatter everywhere, blinding other road users and not doing their job of lighting up the road in front of you very well

That's the kind of nerdy thing I want to watch bruh ❤ thanks for the video

Thank you! Very informative and interesting.

Believe it or not the Citreon DS had headlights that turned as your turned the steering wheel back in the 1950s.

[@horvathr95]

Wrong. The DS was indeed introduced in the 50's, but the turning headlights only came later on in its life

[@Andronicus2007]

@@horvathr95 How much later? It was still a long time ago.

[@horvathr95]

@@Andronicus2007 just google it, probably in the 60’s early 70’s

I hate when people just sit in their cars while its parked with the headlights burning.

The main problem with LEDs is that they are disgusting looking. 12:00 illustrates the obnoxious flickering. Some literally make me nauseous.

[@davidpowell3347]

Some household and even flashlight LEDs seem to have a buzzing or strobing quality

[@thepenultimateninja5797]

The weird part is that they don't have to be that way. It's possible to have an led that gives off a natural looking light. The problem is, the colder the color temperature, the brighter the light appears to be, so they always choose those sickly blue-white leds. I have an led flashlight that has about a 3000 K color temperature, and is 'high CRI', meaning it reproduces colors very naturally. The light it gives off is warm and beautiful, and the high color rendition makes distant objects easier to make out. I think this style of led would be much better for headlights, but unfortunately, they don't look as cool as the bluish ones (both figuratively and literally).

Interesting video. I remember when xenons first came out in the mid 90's, I think the Mercedes E class was the first car to use them widely. They immediately stood out from other vehicles due to that blue/white beam.

[@donberg01]

I converted to halogen headlights back in the 70's from the standard sealed beams. The archaic American lighting laws I thought were outdated. I change when my friend had a European Ford & showed me how great his lighting was, I was sold.The funny thing was American drivers weren't used to the whiter light & would flash me when I had my low beams on!

@TH3C001 It’s NOT good, that’s the whole point. So many of these so-called educational videos are full of falsehoods galore. Those of us who actually know about the subject catch the errors, but the people who these videos are made for DON’T know that what they’re watching is often wrong. But people think it’s right because it’s well made and sounds/looks good. “Artificial Intelligence” means the total dumbing down of society.
