This right-hand rear combination lamp provides tail, brake, and turn-signal functions for the host tractor. It mounts to the rear fender or chassis bracket and connects to the vehicle's 12-24 V electrical system. The lamp housing is sealed against moisture and vibration. A cracked lens or failed seal allows water ingress, which corrodes the bulb contacts and causes intermittent or total light loss. When replacing, verify the mounting-hole spacing matches the bracket and use the specified fasteners to avoid stress cracks in the housing.
