Blazer C6421 Submersible Trailer Light Kit is designed to meet DOT requirements for trailers under 80 inch 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 and are replaceable with Blazer model numbers B81 and B91. The kit includes 2 submersible stop/tail/turn lights, wire harness, license plate bracket, mounting hardware, and trilingual instructions – everything needed for easy installation. Additional side marker lights and reflectors are necessary to fulfill legal requirements. Blazer International is a leading provider of DOT, SAE FMVSS108, and Canadian CMVSS compliant and approved vehicular lighting products for heavy duty trucks, trailers, and RVs. With brands like Blazer, Axxent, BAJA Tough, and Radiant Effects; and over 50 years supplying vehicular lighting Blazer International has built a strong legacy of quality, value, and customer service.
