It serves as the primary connection point between a tractor and trailer, linking the lighting, turn signals, and auxiliary power systems. The Phillips QCS (Quick-Change Socket) design features bullet terminals and a locking clip that allows you to snap in a new socket without cutting or splicing the main wiring harness, making roadside repairs much faster. Its STA-DRY internal moisture barrier prevents water and road salt from corroding the wires, which is a common reason for replacing these sockets when lights start flickering or stop working.
