The tail light circuit board forms the electrical pathway between the harness and the lamp bulbs. Over time, contacts on a board can burn, corrode or crack. If a failed board is the cause of a dim, flickering or dead tail light, this direct-fit replacement is intended to restore proper tail light function. Check the bulbs, sockets, ground and wiring first, because a fault in any of them can cause the same symptoms.
