Hey everyone.
I just wanted to know if anyone can tell me the laws regarding headlights for bikes that have colors other than white/yellow.

There's a product out there that casts a green projection on the ground from a mounted headlight, to alert pedestrians or drivers of your presence a head like...I don't know, maybe 5-10 yards ahead.
I was watching a video about it and in the comments people were saying that anything other than white or amber colored for a headlight on a bike will get you a ticket. Someone said that in the UK it's okay, but not in the US.
Is this true?
I would think it would be illegal for a car OR a bike to have a headlight other than white. It's a distraction right?
But is there an exception for a bicyclists?
And if not, does it matter that the light would be pointed down at the road to project the image?

If anyone can help answer this question it'd be greatly appreciated, thanks.
