It might just be me, mainly because I drive an "old" car that doesn't dim/adjust my rear view mirror based on others drivers lights, but I find the uber brightness of other drivers lights to be a real pain these days. Often on the motorway I struggle to see ANYTHING as i'm being constantly blinded by other drivers high power lights behind me and when oncoming. I get its meant to be a safety feature, but for a lot of other road users it's a real nuisance to be blinded on a daily basis.

A good solution would be for modern cars to detect ambient light and adjust accordingly. On a well lit highway with lots of other road users, there's no reason to have these things turned up to 11 all the time. They could safely dial back to 3 or 4.

I have a VW with xenon projectors and the self-leveling feature should ensure this doesn't happen, but occasionally people do flash me. I assume their eyes are dilated from the weed.

Well the problem is how low is the other vehicle? A modern Range Rover sits much higher than an MX5.

You mention this, but a smart self-dimming rear view mirror can't help at all against the incredible brightness of oncoming headlights. I have been literally blinded while going over CA highway 17 at night (don't let the "highway" designation fool you; it's a twisty mountain road abutted by cliffs), an obvious safety issue.

I don't understand why it's legal to have headlights so bright. Manufacturers say having headlights brighter than everyone else makes you safer because you stand out. By the point where no one can even see, any putative safety benefit has been lost. Headlight brightness seems like a close analog of overfishing to me. :/

Yeah, thankfully I have a dimming rear-view mirror.

Get sick of the comments about being blinded. Wusses this is entire emotion and subjective. Go to a country where everyone uses the brights always like the DR and realiZe no one is blinding you you are just a crybaby.

The problem is not the brightness, IMHO. The real problem is that, at least in the US, no one seems to care about keeping their headlights aimed properly, which in combination with the abundance of trucks with headlights mounted higher than a normal driver's head, leads to insane glare. As much as mandatory vehicle inspections are annoying, this would be my one reason to support them. (Not that it seems to matter, here in HI they have annual inspections, but the inspection facilities don't seem to give a damn.)

Of course, a brighter misaligned headlight is worse, but an old halogen headlight creates plenty of glare if misaligned, while a super bright headlight is fine as long as it's not aimed at your eyes.

The biggest problem is how well are the other vehicle's headlights aimed. When i'm on the highway at night, i find that the Mercedes and Range Rovers with their HIDs are never an annoyance, because the lights shine at the ground rather than into my windows. GMC/Chevy SUVs and Pickups seem to be the worst offenders - they've got the xenon lights, but they're just a drop in replacement for the standard headlamps, so they shine straight out in front.
