Blue is the worst possible color for headlights, from a biological standpoint.

In the human eye, green is the best-processed color. That's why night-vision displays are green - your eye can best see those colors. Red does not do as well, but also does not wreck your night vision.

Blue light is used mostly to tell what color things are. You DO NOT have the same depth perception with blue that you would white or even green light. and you DO NOT have superior visibility in blue light to yellow - the only reason you might see any better is because it is brighter.

You're blinding other drivers, whose night vision is completely wrecked by that stupid blue color. They ought to be illegal.
