| > Second, there's a decent sized market for cheap, unapproved HID/LED kits for older cars. They're often not aimed correctly. This is the biggest problem. Even talk SUV headlights from the factory must meet standards for masking off light and the angles at which they can illuminate. But when people buy LED retrofit kits and jam them into reflectors not designed for those bulbs, the reflectors don’t mask properly. Light spills everywhere. I would bet that nearly all of the “headlights are too bright” complaints are coming from people seeing LED retrofit kits. |

| Those are some of the most offensive lights but I wouldn't say it's the biggest problem. SUVs and trucks often have their headlights at the absolute highest point allowed and it's not uncommon for drivers to install lift kits which raise the lights even higher. If you're in a standard sedan, headlights pointing into your eyes is pretty unavoidable. Even a small vehicle that's oncoming and on a steeper incline than you may shine their bright headlights into your eyes. There are no government agents going around inspecting all the vehicles coming off the factory line. Anecdotally, my friends Tesla has completely horizontal headlights from new. I could see oncoming drivers faces illuminate and wince in pain. A quick adjustment in the settings fixed that, however the majority of drivers are ignorant of the fact that headlights are usually adjustable. Not sure there is any real solution other than going back to halogen lights or requiring sophisticated anti-dazzle systems. |

| > I would bet that nearly all of the “headlights are too bright” complaints are coming from people seeing LED retrofit kits. Disagree. The "too bright" headlights are new cars. And sedans as well as trucks SUVs. Another big problem is that the lights are much closer to "point source" than older headlights which were 4-6" in diameter. A modern headlight is more like a 2" or smaller diameter projector lens, which is even more blinding. |

| How many people are really getting after market headlights installed on their SUVs? There's too many vehicles with blindingly bright lights for that to be the cause. |

| ▲ | thewebguyd 5 hours ago | parent | next [-] | | I used to think it was a lot of people doing it. I drive an older car with what I call "normal" brightness headlights, and the warm color too instead of the annoying blue/white. But then I had to rent a newer car, and it came stock with super bright blue/white headlights. They were so bright to what I was used to I had to double check the high beams weren't on. The standard lights were as bright as my old car's high beams. Lights in newer cars are literally just that bright, and I think it's a result of car safety culture being a matter of "I only care of the car protects me" instead of "the car should also be safe for others on the road as well" | | |
| ▲ | hn_acc1 an hour ago | parent [-] | | I mean, I have those types of lights on my car, but I am VIGILANT about checking that they have a slight DOWNWARDS slope (and I'm in a relatively low sedan to begin with). There's a T-intersection near my house with a retaining wall at the end - very convenient for checking the angle. Even when I upgraded my old car to HIDs (because I could barely see anything over the other cars), I checked over and over to make sure I was low enough. Also, I ensure I never light up the TOP crease of the trunk of any sedan behind me. If I light up anything inside another car, it's bad. |

Guess how many owners actually figure it out? A vanishingly small percentage.. (or they're all assholes who want to blind others on purpose) | |
| ▲ | jcranmer 5 hours ago | parent | prev [-] | | When my taillight burned out, I went to the local autoparts store to get a replacement. The first light I picked up had printed on the packaging, in not-terribly-visible writing, "For Off-Road Use Only." I had to go back and hunt longer for the light that was legal for road use. There's probably a decent contingent of people replacing their lights with out-of-spec lights not realizing that the lights are not actually road-legal. | | |
| ▲ | potato3732842 4 hours ago | parent [-] | | That's not how it works. They can write whatever they want on the packaging. It's the final assembly that's compliant. They're covering their ass in case you put their 5W bulb in some application they've never heard of where it technically fits but a 2.5W bulb was supposed to be used or something. It's like how aftermarket brake hoses all say "off road use only" despite pretty much all of them vastly exceeding the FMVSS for brake hoses. | | |
| ▲ | yesb 4 hours ago | parent [-] | | The correct bulb will not say that, aftermarket LEDs do. The light reflector housings are designed and tested for specific bulb standards. There are LEDs which try to output light from the same place as the filament in the bulb they are mimicking. But there is no guarantee they function properly, hence the warning and illegality. If you swap one side and walk around your car, you may see that they are significantly dimmer than the stock bulbs from some or all angles. Or it may work fine. Often times the aftermarket LED dual intensity tail/stop lights have barely any difference between the two brightnesses which is egregiously unsafe |

| No, new cars are actually just ass. |

| Aren't there any checks for that? In EU most DMV equivalents check headlights yearly to catch illegal illumination envelopes (along with other safety-related aspects, brakes and whatnot). |

| ▲ | toast0 4 hours ago | parent | next [-] | | Most US states don't have an inspection regime. Of those that do, it's often just for emissions (and with 2001+ cars, it's increasingly just confirm the check engine light shows up in the light test and turns off when the engine is started, plus check that the emissions computer says ready for test). The driving public does not want to pay for safety inspections. But yes, if there was a safety inspection, it should include verifying that lights function and that headlights are aimed appropriately. A brightness test might be too complex, but safety inspection would be the place to do it. | |
| ▲ | alistairSH 4 hours ago | parent | prev | next [-] | | In theory, yes. But, it's state-by-state, enforcement at drive-time is next to zero (unless the cop just wants to hassle you), leaving it to either annual or time-of-sale inspections that are easily gamed (slip the mechanic a $20). Heck, people will reinstall stock parts for inspection then swap back to the illegal parts. Common with emissions stuff as well. | |
| ▲ | yesb 6 hours ago | parent | prev [-] | | Only a handful of US states have any type of safety inspection | | |
| ▲ | eszed 5 hours ago | parent [-] | | The only one I've experienced (Massachusetts) wouldn't catch any of what we're discussing in this thread. They put it on the emission testing machine, walked once around the car, maybe checked the brakes, and that was it. It was in no way comparable to the UK's MOT test, which is a proper inspection. | | |
