Are under the car lights legal in New Jersey?
Yes, assuming they aren’t turned on. The exception is red or blue, which is illegal even if not turned on. Under traffic laws in most states, drivers may be given a traffic ticket for operating a vehicle that has been modified in violation of laws that regulate vehicle specifications and vehicle equipment. Examples of vehicle modifications that may result in a traffic ticket include: Addition of non-standard lighting (neon lights, under-vehicle lights), Alteration or removal of air pollution and emissions control device Modification of vehicle ground clearance (“lowered” or “raised” vehicles), Removal of mufflers and other sound-control devices, and Window tinting (especially tinting of windshield or driver/front passenger side windows).
