The TecLoq lights feature an all new, locking interface with a bracket design that locks the box tail light into place with no fasteners necessary. The T89 box light is an 8 function light (left side includes license plate light) and/or 7 function for the right, including stop, tail, turn, combination side marker and clearance lights, as well as rear and side reflectors. These lights are SUBMERSIBLE!
