Blazer C7423 LED Submersible Trailer Light Kit is designed to meet DOT requirements for trailers under 80 inches wide. This kit is not only ideal for boat trailers but for any utility camping snowmobile and motorcycle trailer where LED lights are desired. The life of an LED trailer light far exceeds traditional incandescent trailer lights. Lenses are sonically sealed to provide protection from moisture and corrosion. Additionally all electronics are potted with water resistant resin for a second layer of defense.
