TOO BRIGHT Car Headlamps!?! | Laser LEP vs. LED vs. Halogen | Stronger than Sunlight

[@Michalloyd_stop-motion]

modern car headlights are so bright that at night I keep thinking everybody has their high beams on even though they don't.

[@ashliehiggins]

They aren’t any brighter than the Xenon/HID lights which have been on the roads since the 90s, you just don’t like the colour temperature.

[@CristiNeagu]

That's also because people don't align their headlights properly, or they put the bulbs in upside down, or they use the wrong bulbs. This last one is a problem with LED replacements, as headlight mirrors and lenses are tuned for filaments, and they don't focus the beam properly with LEDs.

[@martinweizenacker7129]

@@CristiNeagu Exactly what I have observed with LED retrofit lamps. Unless the light emitting surface is shaped and positioned inside the headlight like the filament it's supposed to replace, the beam pattern is going to be different. As a result, there may be undesirable light spill above the cut off threshold (blinding oncoming traffic).

[@WaltRBuck]

Same, it has kept me from driving during busy times at night. It's absurd.

[@luis241661]

alignment. standard headlights, no matter how new or bright, shouldn’t be blinding. they’re typically pointed slightly downward. unfortunately most ppl don’t know how to align their headlights or kno to take their car to a shop. there are some exceptions! tall trucks/vehicles and the newest teslas. for some reason the new teslas r either not correctly aligned or there is a design flaw.

[@michaelpmalin]

2:15 - These should actually be designed for more like 13.5v to 14.5v as this is the normal operating range for a car. If your car is at 12v running, your alternator is no longer with us, my condolences.

[@hanswurst-h3e]

@@jonny11bonkDont know for new vehicles, but historically they relied on cheap thin wire for some voltage drop to not wear out the bulb in a couple hours.

Ok, what if the high-beams are like looking at an arc welder but the low- beams are still as bright as the sun? Doesn't matter.

[@papaquonis]

This is not only a problem in traffic. As a train driver, this is something I occasionally have to deal with as well. They recently started using some absolutely ridiculously bright lights on some of our trains. We obviously have quite an advantage on the rails, since we're in no immediate danger of going off the road like a car, but getting blinded sure isn't optimal for us either.

[@butters2160]

actual car voltage when the cars engine is running is higher than 12v so you should be testing the headlights at 13.8-14.2 volts. the battery is 12 volts but the alternator produces this higher voltage to charge the battery. would like to see how much this changes the brightness.

[@CompoundBoy]

Correct, but as he mentioned in a previous video, LEDs and LASER diodes require a limited or constant current source (due to thermal runaway); so for LEDs and diodes I doubt it would make a difference since the driver might deal with it. For incandescent and halogen: it is proberbly worth it .

[@nZoot]

Doesn't matter with LED as the voltage is resisted down to its wanted specification.

​@SoloRenegade I have one of the first years of the huge trucks. Mine is not lifted as much as some but it doesn't matter. I changed the halogen projectors to HID and put the brightest ones I could find 50 watts. At first I didn't get the aim right and I got flashed a few times. Once I got the aim right nobody ever flashed me. LED now put out that much light, so I know it is a control issue mostly. New stock ones are not laser bright, so the aim is off or the beam control is crap. If they lift a truck they should still only shine out 160 feet, so you should only get bright when you are 80 feet or less in front of them, basically just as you pass. When they lift a truck they have to aim down more, but probably dont change anything. Every manufacturer has their own strange way of saying how to aim them and it only applies to that vehicle which is stupid. I have a better way for Every vehicle no matter ride height. Need a flat surface long enough for the vehicle plus 16 feet in front. Measure the hot spot height as close as you can and then 16 feet in front it has to be 90% of the close height. If it is higher, it blinds people way more often. I wonder how many people will read this, not zero, and how many will check and adjust their own, maybe zero?

The biggest issue is people retrofitting new LEDs into old headlamps - the LEDS are not in the same place the filament is in a halogen, meaning an instant misalignment of the light being way too high. and just for good measure, way too bright too

Great video as always! Just a quick remark on the LED and laser examples shown: they do not obey to any of the design constrains (or specifications, if you prefer) of the housings they are supposedly designed for. This is because on reflector style housings, the position on where the light origins from is critical. All those intricate shapes on either the glass (older style) or shiny silver reflective coating at the back of the housing aren't random, but very specific and were made expecting a precise light source location, that is also pretty small (aka the filament). Those LED replacement bulbs you see a lot of that are cheap knock-offs don't account for that and will result in either a terrible and unusable light beam pattern for driving, not illuminating the road, and/or blinding everyone else, which is already a very prevalent issue. If you want an LED replacement for your car, look at brands the like of Osram or Phillips. They even have road legal versions now, but even the others are incomparably better (from personal experience). You will pay decent amounts for them, but IMO, if you don't want to open up the wallet to that extent, you are better off with good old halogens.

[@jandl1jph766]

The LEP module isn't a H4 plug-in, it's a proprietary design for use in specific models of (mostly VW and brands, if I remember that right) cars. They are aligned correctly, but still *far* brighter than they should be.

[@tuxrandom]

9:30 - The cyan / green tint is a dead giveaway for cheaply made phosphor based light sources. Interestingly, the LED could still fulfill a CRI of 95 while absolutely disfiguring reds, because the CRI (Ra) doesn't properly account for reds (the test colors are a very washed out rainbow and the "red" is the worst of them). For a proper white light source, the R9 (CRI for saturated red only) is a crucial measurement in addition to the Ra. Re (14 colors) and TLCI are even more accurate.

Even on coming, sometimes they're not too bad until they hit just the right angle and then it's blindingly bright. Other times you swear people have their brights on when they don't but then they have two headlights on two running lights and some fog lights so it's no wonder you're getting blinded. Plus some vehicles have stupidly bright brake lights and turn signals. It's seriously like looking at an orange strobe light when you're behind one of them at a stoplight.

But another big issue these days is the love for big cars some people have People now want these bigger SUVs and this means those headlights are installed higher on the car and if you have an older sedan/hatch, those lights are now shining in your face due to them being higher up.

[@MrPabsUk]

That LEP puts out a crazy amount of light, its scary to think people are putting them into cars. I hope it doesnt get popular! I drive low, traditional height cars, I`m constantly blinded at night, particularly when someones coming towards me in a modern LED headlight car, & especially MPV/4x4/van height vehicles, on the other side of the road, around a long, slight angle bends. Also, when approaching or going over the peaks of hills I`m often blinded by cars coming the opposite way. There's also a LOT of people with misaligned headlights, I`m sure a lot of them have been hit when parked, moving their vulnerable headlights, & most drivers don't check their alignment when they use them & don't realise the headlamps have moved (its easy enough to check the headlight alignment on the back of busses etc every time you drive with them on, but few people seem to think to do it). There's rules about having headlight wash & automatic (suspension mounted) height adjustment when HID & LED lamps are fitted across Europe, but obviously that doesn't help if the headlight alignment has been pushed out after minor parking knocks, & doesn't solve the hill/long bend problems, even in brand new, undamaged cars, at all.

[@denvera1g1]

The problem with the new lights isn't just that they're brighter, but the color is shifted so much towards the blue. At night, dark adapted eyes rely more on rods than cones in our retinas, and those are more blue-sensitive. I'm a life-long amateur astronomer and we use red lights when needed since it doesn't affect dark adaption as much. Blue lights at night are much more "dazzling", even if at the same brightness.

[@Laralinda]

And now combine it with "automatic high beams" - they just don't work. The seller of course tells you that it automatically dims the high beam when other cars are around, but in reality they shut down too late or not at all. Of course you can switch it to manually, but people are overwhelmed. 1 million assistants build into their car, everything wants to help you with comfort and driving, but in the end you don't find the switch to gain control yourself. So people go with "nah, the car knows best".

[@ATTACKofthe6STRINGS]

The automatic high beams should be customizable, but that requires somebody going into a menu on their car to set it up, which is the real problem. So many things are behind some sort of menu that shouldn’t. I actually set up my car’s automatic high beams to be one or two ticks more sensitive than whatever it came with by default, because I was bothered that they didn’t come on quick enough in the dark, and didn’t turn on fast enough when a car showed up in front of me. But not everybody is me, and not everybody wants to program their car. Not sure how it is on most cars by default, but you need to actually push the light stalk forward *and* have the selector set to “auto/DRL” in order to get automatic high beams. I would hope that every manufacturer would also work to have the automatic high beams not be so easily set. I also just turn off my high beams if I see they aren’t reacting to oncoming traffic properly. But, again, I know not everybody is me, not everybody should be me, and this is ultimately a problem of car manufacturers not designing interfaces and features well instead of a user problem.

Not only cars are an issue here. Plenty of bikes and especially e-bikes that ruin your ride at night or in the morning. Even when I cycle to work and back, sitting higher than in my car, about 60% of the oncoming cyclist have their lights pointed to ... I have no idea but not on the road. A lot of them are not using the StVZO standard or they just misalign them since it is just twist to misadjust them instead of a screw or motor on the car which makes it a lot harder. There is no good about proper optics when they can not be enforced.

Wow , really nice video , the voltages on a standard running motor car are from 13.4 to 14,5 V , and it's true that light's are getting brighter , for me the worst is when someone don't set correctly the beam down and to the side , blinding incoming trafic . some car's uses alternating filaments in a bulb like H4 , others uses both filaments from 2 separate bulbs like a H1+H7 . Xenon lights are very nice , and even nicer if it's a directional beam headlight, and LED's are also very nice , but in some cases if the car maker uses 2 separate simultaneous LED low beams side by side with slightly different angles (Front+side) , in certain angles like crossing in a top a hill makes a lot of incoming drivers think you are on high beams , until you flash them to show you aren't. The LED and Laser headlights are ok , if they use adaptative tech , using the camera to adapt the light to not illuminate the spot were the other drivers are , very high tech stuff . Liked the Lego space shuttle and Hubble telescope , I have the same :D

The issue with LED bulbs blinding everyone is that they are not compliant with the bulb spec the reflector housing was designed for. The reflector is designed for a bulb that has a filament in a very specific position, and if there is any deviation from this position, the reflector housing will not position the light correctly and end up blinding everyone. Many LED bulb makers do not even bother trying to stick to the bulb specs, especially the super cheap ones on Amazon that everyone buys.

In my country, it's not only about the lumens, it's also about the light trajectory. Even a fairly low lumen lamp such as halogens, can be blinding if the reflector is not properly adjusted. Much worse with the LEDs, since the reflectors themselves seem to project the light at much too high angles, especially exasperated when cars are coming over hilltops! There will have to be a better solution in the future... Self driving cars would cure it, but that's decades away... Only thing I can think of is adaptive windshields in every car made, like they did with seatbelts and airbags, and unfortunately, even that would be decades away, but a lot cheaper and easier to do... 🤔

One day i became terrified because after a very big light exposure a dark spot appeared on my left eye and it took almost 3 weeks to fully disappear.

Another thing to note is that cars worth led standard headlamps have reflectors/housings designed for them, the generic reflector/housing he used for the test is not designed to properly disperse the led light so it's less effective.

I'm not sure what you are talking about, lots of new cars have safety features for protecting pedestrians. From the shape of the front and the height of the bumper to sensors to stop the car before it even hits someone. Cars today have never been safer for pedestrians. Vehicles today could not be called "tanks" as a lot of them have their entire front ends made of plastic. We are no longer in the age of the massive steel 5 mph bumpers from the 70s. Cars hitting pedestrians however is not an issue with the car. It is an issue with people not paying attention (or attempts at insurance fraud).

[@SantaClaw]

The most important factor for headlight lamps, is the location and size of the filament/LED. The reflector in the headlight, is made to reflect light that is coming from a very precise location, changing it, even by a few mm, will make your light very inefficient, and it can/will distort the light making it blind oncoming traffic, and illuminate the wrong parts of the road. High beams, are made to project the light a long way away from the car typically up to 300m. You are supposed to keep your vision as far from the car as the light can project, aka when driving with high beams, you should focus as far ahead as you can .If you have your low beams on at the same time, they create a bright spot directly in front of your car, this will make you naturally focus your eyes on that spot. The brightest spot will typically be around 50 meters ahead of your car.. When driving at 80 kph for example, you are traveling at approx 22 meters per second. That means, if you are concentrating at the area where low beams illuminate, you have around 2 seconds to react to things that come into the lit area. On avg, a human take about 1.6 seconds to spot a hindrance, think about what to do, and start doing it. Leaving you about .4 seconds to actually brake, steer, etc. It takes time for you to push the pedal too... If you are using your high beams correctly, and your vision is 200-300m ahead, you will have plenty of time to react.
