My parents tell me back in the day you use to have to get your head lamp aligned and proper alignment was required to pass state inspection, at least in VA.
I too have seen blue, pink, purple and other off white colored lamps I think should be for car shows or off road only.
Having said that, we have a lot of people who have no consideration for others and drive with their high beams on. Those cars I slow up on purpose so they can shine on without me in their way.
