For front signals, white or amber are permitted. As for sidemarkers, they must *REFLECT* amber in the front/red in back. That means, when the lights are OFF, they must reflect that color - that is why they are called reflex reflectors. They mark your car when its OFF so other cars can see you (if your car is off or light is burned out).
Since the sidemarkers I sell are custom fabb'ed, I cannot replicate the reflex reflector of the stock lens.. so its clear, and its for offroad ONLY. That is why a LOT of these sidemarkers being sold are illegal. The basic problem isnt the color output, its the reflector color. The color is shines with the lights ON is only secondary.
So, if you do have clear sidemarkers.. keep them yellow, clear, or atleast hyperwhite.. but not blue.

I'm pretty sure that any color besides white or yellow is illegal. All other colors either distract other drivers and are a hazard, or their used for emergency vehicles. Every state and municipality is different though, so check with your local law enforcement. They'll know for sure.</td></tr></table><span id='postcolor'>
