I think part of it is a reaction to the poor bicycle infrastructure in many cities. Bright lights have stopped cars from hitting me at night a couple of times. While I'm simpathetic to other people (I try not to point them in people's eyes) there aren't that many other options.

I live in Portland, OR, e have pretty good bike infrastructure. If the goal is to be seen, there are indeed other options. LED glow or area lights are probably more effective than the eye melters pointing towards the sky and much less hostile.

Based on what?

Color other than white, large area illuminated, can be seen from any direction. All these contribute.
