In Europe, this is hardly a problem. I’ve recently been on the road more in the US, and it sucks. But I think it’s more so due to cars being ridiculously big and their lamps being way off the ground.
With halfway decent power stabilization, and the appropriate about of directionality in the lights, plus the lights being somewhere below the typical sedans window frame, the only time headlights should bother you, is when you're on a hill, regardless if they're LED or not.
IMO, one of two things is very wrong if you're getting blinded by anyone's headlights (highbeams not withstanding): either the designers and engineers that worked on the car are idiots, and placed headlights in a location that was going to blind people, or they used crap optics, etc.... Or, the owner of the car can't be arsed to have their headlights properly adjusted.
Honestly, it's a little of A and a little of B... Depending on the car and the circumstance.
One the person I knew actually had self adjusting headlights, which somehow were damaged and would not adjust properly anymore. They drove around like that for years before retiring the vehicle.
The new trucks in America are all blinding because of how high off the ground they are and the ridiculous number of lumens. It's like manufacturers just want bigger number, bigger number = better, lol.
I drove past a car that had its headlights flickering about 15 times every second last year. No clue if it was intentional but it was distracting as all hell. (and probably dangerous to epileptic people)
Congress could easily pass a lazy maximum brightness law but we're too busy stalling a mostly approved daylight savings law because some asshat party leader(s) is waiting to slap 200 riders onto it like another morbillion dollars of tax money to Israel.
It's so bad people put here are getting illegal windshield tint just to reduce the insane glare.
Of course a real solution would be a proper regulation with tickets for anyone running incorrectly adjusted headlights or anything that is basically acting as a high beam.
I’d say this ‘chat’ should go to GM and their stupid ideas to point fucking headlights straight into the mirrors of cars ahead of them. Only one of the few hazards they cause on the road today.
There was nothing wrong with the halogen and I'll die on that hill. Ever since they abandoned it, it's been an arms race, and the aftermarket drop-ins are the worst offenders. I've resigned myself to never seeing anything on the highway shoulder because of the intensity of oncoming traffic's headlights.
It's mostly the color of the light that's the problem right? Our brains register the cooler light in the contrasting darkness as blindingly bright as opposed to warmer incandescent light, despite both lights having the same measured brightness (lumens).
Man I want to put LED bulbs in my 1999 model year car, but I don't want to start blinding people. The last thing I want is for someone to hit me because they were blinded. It seems many LEDs do intend to have similar beam patterns to halogen bulbs, but I'm not sure how well they actually do.
Our 2020 Mazda has LED headlights, and I gotta admit, they are much better for seeing. We live off the beaten path, not a ton of traffic, but plenty of deer and other animals.
On the other hand, my headlights in the 1999 had gotten really hazy, and I recently did one of those headlight restoration kits to it, and it worked stunningly well. Since then, I haven't driven at night very much to get a feel for how much it helped. So maybe I won't need LEDs. (The halogens in there are relatively new.)
You can't go and kill the guy at a point where you know he has events in his yet. (A person's "yet" is what is known of their personal future). You have to attack him at a point where you he doesn't have any events in his yet that you know about. This also means no killing Hitler before April 30th 1945.
