Even bicycle headlights are now getting so bright that I find them to be painful [1]. Unlike cars, their placement isn't regulated at all, and many cyclists seem to think that pointing them slightly upwards is a good thing. Or worse, they'll wear helmet headlights which are pretty much at eye level.

[1] I'm a bit more sensitive to light than most people, I get migraines and have low grade photophobia 24/7.

I believe the U.N? had to update their guidance for this reason. Iirc, the max allowed brightness was either calculated incorrectly, or was just set too high.
