This rear lamp is a lighting component for the rear of the host tractor. It provides illumination for work operations and increases the machine's visibility to other traffic. The lamp is part of the tractor's electrical system, connecting to the existing wiring harness. As an original component from the tractor manufacturer, it matches the housing geometry and mounting points of the original assembly, allowing direct replacement without modification. A failed lamp results in reduced rear visibility during low-light operation and may cause the machine to fail road-safety inspections. When installing, ensure the connector is clean and fully seated, and verify that the lamp housing seal is intact to prevent moisture ingress.
