yes, as are tinted windows and modified exhaust. I live in California, probably the worst state in the world for modifying cars, and I have never had a problem. that being said, if you drive like an idiot or give them a reasin to pull you over, you are probably going to get a ticket for the lights as well.
these lights are in perfect condition. as stated, they are painted in a booth similar to where a car is painted. there are no runs or imperfections and they are clear coated to match the gloss of the car.
