The submersible trailer light kit is designed to meet DOT requirements for trailers over and under 80" wide. This kit is not only ideal for boat trailers, but for any utility, camping, snowmobile and motorcycle trailers. The "Bell Jar" design prevents water from coming in contact with bulb or socket. Additionally, the lenses are sonically sealed which eliminates the need for gaskets that can dry rot and leak. The stop/tail/turn lights feature universal back & side mount options. The lights are replaceable with model numbers B84 and B94. The kit includes 2 submersible stop/tail/turn lights, wire harness, license plate bracket, mounting hardware, and trilingual instructions- everything needed for easy installation.
