Nearly all UK drivers say headlights are too bright

I feel the same way in America, I think there should be stricter regulations on how bright a car's headlights are allowed to be for it to be street legal. Wouldn't mind having a cap on blue-light levels in addition.

Ooooh so I am not the only one to swear at those blinding headlights? Interestingly (or not), I think there should be a regulated height for the headlights all private cars; I drive a B-segment type of car, and I find all those European SUVs have their headlights right at my shoulder level meaning I will always be subject to be blinded by this type of vehicle vs a similar lower car. That goes for the vans as well.

Meanwhile, brake lights and running lights are frequently too dim because of an aesthetic obsession with "blacking out" tail lights.

Where are the AR driving glasses that automatically dim oncoming headlights (and alert the driver to possible road hazards, and…)?

Seems to me that all of this tech to create autonomous driving could be also used to augment human driving.

I understand that currently this is sort of a collective action problem, but I'm a bit baffled why people ever thought they needed brighter headlights in the first place. In the city, it's so bright that you don't even need headlights to see whatsoever. When cars started automatically dimming the dash via a light sensor, there was actually a period of time where I totally forgot to turn on my headlights because things were so well lit -- even at night -- that I didn't need them whatsoever.

Out in the country, you still don't really need brighter headlights. Other cars' headlights will always be visible and they have reflectors, so it's not as if you'll struggle to spot other cars. The road lines are actually reflective, so it's not as if you'll struggle to see the road lines. And generally speaking out in the country, there won't be pedestrian foot traffic, so it's not as if you need the bright lights for them.

So who are they for? I think broadly people may just not be able to avoid excess unless restricted by the facts of their environment. Allow people a plethora of calories, they'll get too fat. Allow them a plethora of entertainment, they'll drive themselves insane. And somehow .. allow them too many bright lights and they'll all just blind each other.
