The Wesbar Waterproof Red LED Wrap-Around Trailer Tail Light functions as a Stop/Turn/Tail lamp and is intended to be used on trailers over 80-inches wide. The wrap-around design of the trailer light eliminates the need for a rear side marker/reflector and is designed for 2-feet or 4-feet wide x 4-feet high areas. The tail light includes a plug-in 12-inch harness with 2 way flat connector and ring terminal ground wire. Stainless steel mounting hardware included with wraparound lights. Wesbar trailer lights meet FMVSS/CMVSS 108 requirements. Wesbar Right/Curbside Waterproof Red LED Wrap-Around Tail Trailer Light (281594) also available (sold separately).
