Yeah, about 15 years ago when LED headlights started to appear I noticed that they absolutely nuked my night vision. Now they're everywhere and driving at night is kinda scary because you know that unless something is explicitly illuminated you won't see it until it's on top of you.

I think it's their white violet color that makes them a huge problem, though. Because I've definitely caught yellow brights from a pickup late at night on the highway and it wasn't as bad as getting an eyeful from a late model car as they went over a hill. I'd like to see a bill that makes blue light filters mandatory on vehicles.
