This rear combination lamp provides stop, tail, and turn-signal functions for the rear of the host tractor. It mounts to the fender or rear chassis panel using the two M5 fasteners through the 45 mm hole spacing. The lamp operates on either a 12 V or 24 V electrical system. A failed lamp is indicated by a non-functioning circuit, which should be checked by verifying voltage at the connector before replacing the unit. When reinstalling, ensure the gasket between the lamp housing and the mounting surface is clean and undamaged to prevent moisture entry.
