Our MaxxHaul 50520 12-Volt LED Submersible Trailer Light Kit has multiple useful functions such as for stopping and turning, as a tail light, as a rear or side reflector, as a side marker light, or as a license plate light. It is compatible with towing vehicles such as boats, trailers, trucks, etc. that are under 80 in. The wiring harness is made from 18-Gauge 100% pure copper wire to ensure a reliable and long-lasting product that remains effective even underwater. It is also designed with LED instead of incandescent lights, further adding visibility and providing a much more energy effiicient product. They are sealed using sonic welding technology to prevent any liquid or debris from entering and to secure the lights while being used underwater. The compact size of the trailer lights provides further portability and the attachable bolts guarantees easy installation on either the rear or the side of your vehicle.
