Wow! So much discussion on headlights, I want to add my two cents. Working graveyard for 14 years, I always had to deal with bright headlights. One night, I was being blinded by an oncoming car. I flashed my brights, no response, so I flashed them again. That car was a cop - hit his flashing lights, turned around, pulled me over. He came on real strong, until he saw my dash cam on, then just gave me a warning. Thinking about it after, I realized they probably have their headlights high, to see licenses at night. What I have to deal with now, is all the big pickup trucks that had lift kits installed, but never adjusted their lights.
