The LED submersible square trailer light kit is designed to conform to applicable US FMVSS108 and Canadian CMVSS safety standards for trailers over and under 80 in. 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 lasting up to 100,000 hours and no bulb changes. The lens is sonically sealed to provide protection from moisture and corrosion. Additionally, all electronics are potted with water-resistant resin for a second layer of defense. Lights are individually replaceable with model numbers C7483RTM and C7493RTM.
