i'm not 100% on it, and it may vary from state to state, but that's the big thing with the aftermarket 'euro' tails... the reflectors arent correct as per mfg specs. (typically deals with either non existent or differnet location reflectors), but also deals with the clear corner issue (supposed to have amber reflectors in the front) but i can bet that having a reflector that doesnt reflect like it should (or is wrong color) would be a problem too. -- but i've gotta think that if your eye can see the reflector, then it'd be alright.
