This rear combination lamp provides the lighting functions required for road travel and field operation on the host tractor. It integrates stop, tail, and turn-signal elements into a single sealed housing. The lamp mounts to the rear fender or chassis bracket and connects to the tractor's 12- or 24-volt electrical system. A failed lamp reduces visibility to following traffic and can cause a road-safety violation. The housing and lens are constructed to resist vibration and moisture ingress common in agricultural environments. When replacing, verify the connector matches the tractor's harness and that the mounting holes align with the bracket.
