The newest addition to our Fire & Ice Line is our LED Trailer Kit. It is a 2-Bar kit designed to fit any trailer. The kit features Running Lights, Brake Lights, Turn Signals, and Reverse Lights. The LED Tubes are 100% waterproof so you are safe to submerge your trailer, and they attach to your trailer with high-power magnets so there is no drilling or adhesives required. A 4-Pin trailer hitch adapter is included, so your kit can easily integrate with your truck s electrical system. If you do not have a 4-pin plug on your truck, hard-wiring instructions are included. -Works with All Trailers -Plug-in Design, No Wiring Required -Brakes, Turn and Reverse Signals -100% Waterproof
