You can ban the sale of super high power bulbs, though. all of the bright headlamps fail (even LEDs, eventually…) and they simply get replaced with compliant bulbs.
It is less about the output in lumens of the lamp, but more about the angle and color temperature.
In most cars, the difference between regular headlight operation and "brights" has nothing to do with the output, it's about the angle of the beams. Of course, when you angle the headlights up so you can see farther down the road, now you also point them at oncoming drivers eyes.
The scourge of "blue" headlights amplifies the problem. They're no brighter, but they are more uncomfortable to stare down.
In most cars, there are a variety of ways to fine-tune the angle of the beams with often little more than a screwdriver. The problem is that most people have no idea that they need to be adjusted. This is why regular inspections are important as well as some sort of standards that can be applied across a wide variety of cars.
The reality is that correcting poor angle on headlights is a trivial task, should only take a few moments. Additionally, most modern headlight systems are active and can adjust the angle by pointing the lamp down or using shutters or individual LEDs to change the angle or beam pattern. Eventually, this will just be an irritating thing of the past, but it will take a number of years before every GM truck and SUV is off the road as well as a lot of current Hyundai/Kia products (anecdotally observed by me to be the worst offenders).
LED's generally outlast the car
Not the PCB flea-bay ones. Not ten minutes ago I discovered yet another 194 bulb fritzingTF out on my car that the previous owner had installed. This is the fifth one that has crapped out. I only notice because I rarely drive at night and my car looks like it’s spazzing out.
I work in auto parts. I processed warranty returns for about 5 years as my main task for a while. We didn't get many led bulb warranty/defective returns. Hella, Sylvania, Osram, Heliolite, and can't remember the other brand we typically sell. Those brands have very very few returns that weren't "we fucked up and ordered the wrong part"
Just stop buying cheap shitty bulbs from cheap shitty suppliers
That would be my recommendation as well. I would guess that the temu bulbs fail because they don’t seem to have any practical means of active cooling No heat sinks or other mode of heat dissipation. Couple that with likely bottom-shelf cob leds, and you are now piloting a seizure-mobile.
Myth. LEDs do not last. Led house bulbs also suck, and die all the time. Led headlight literally go out on 2 year old vehicles, ive seen it often, usually Chevy's if i recall.
The whole "led lasts forever" was a scam.
Which brand led bulbs are you buying, so I can avoid them? I have bulbs that I use daily when I'm at home, and a few are getting close to 15 years old at this point.
Feit
So Chevy cant design a proper circut. Check.
They can last forever, or you can push them too hard with too little cooling to save money. Almost all bulbs seem to do this.
Of course bad designs overheating the leds do lead to some cars models (and brands) burning out their LED's, but as a general statement its still true.
My Acura MDX has permanent LEDs, they cannot be changed without buying a complete new headlight assembly. I've been driving it for 11 years and have never had any of them fail. They will outlast the car.
Wasteful and terrible idea for repairability. I'll take my sealed beams and 1176 generic bulbs that are user serviceable. Have you seen the cost of those headlight assemblies ? Also, get in 1 small fender bender or a deer you're looking at maaaasive repair bills now.
Any fender bender means massive repairs. I've been replacing bulbs for over 30 years, it's nice to have great visibility and not having to worry about bulb replacement. I totally get your point, but it's a non-issue for me altogether. I've never had to replace them up to this point, and I'll never have to replace them in the future most likely.
I've driven it for so long at this point if I get in a fender bender it'll be totaled anyway. They're mathematically engineered to last between 41 and 68 years. That's one cost I'll never have to worry about.
Makes sense ! I just dont like non replaceable parts.
I 100% agree with you. I wish repairability was more of a thing so we could avoid more environmental waste, among other things. It also feels nice to fix something yourself.
It gets worse when you combine super LED brights with matrix headlights that are marketed to "allow the high beams to remain on even with oncoming traffic".
