Blinding Car Headlights

Commenters complain about overly bright LED and HID headlights on modern cars, SUVs, and trucks that blind other drivers at night through poor aiming, high mounting, or lack of regulation. Discussions advocate for better auto-adjusting features, stricter standards, and proper alignment.

Because LED headlights aren’t blinding enough?

You don't need to blind other road users. That's a bug with the headlight design, not a feature.

Thats probably because it has ridiculously bright headlights to compensate.

Solution is correct, but you'll never outshine others' headlights shining into your eyes. It's more important that others' bright headlights adjust quickly enough that they do not shine into your eyes. Since the advent on Xenon lights headlights need to automatically adjust so they don't blind drivers. They are just not fast enough or smart enough (shining over a hill crest).

If you are getting flashed, hve the dealer re aim your headlights or reconsider your choice of car. People who blind other drivers should be taken off the road.

It's because of the headlights - they bias right and would blind oncoming traffic.

Can we just make headlights less blinding?

glimshe Jan 10, 2025 View on HN

I've noticed this. My car has one of these bright headlights (I had no idea when I bought it). Its a lot easier to see in dark streets, I'll admit that.But my car also has some electronics that turn headlights down if I'm using high beam when another car is coming my way. Maybe that's the solution, but for the low beam too?

I can tell because Teslas have high pointing headlights that blind me

With the insane brightness now possible I wish they had to meet the same light pattern rules car headlights do. I think that would help the flashing being so distracting.
