lots of people are having HID's now and since they come standard in most high end/luxury cars i dont think cops really pay attention to which cars are meant to have HID's or not... unless its stupidly blue or something.. ive got 8000K HIDS in 3 of my cars with 1 being projector headlight and the other 2 not and not once have a cop say anything about them..maybe if your car has another defect THEN they might ask you about the HID's? otherwise i think its pretty safe
