This rear combination lamp provides stop, tail, and turn-signal lighting for the rear of the host tractor. It is a rectangular unit with a fixed mounting pattern that aligns with the standard bracket on the fender or rear chassis. The lamp operates on a dual-voltage system, accepting either 12 or 24 volts, which allows it to be installed on machines with different electrical architectures. The housing is sealed against moisture and dust ingress to protect the internal reflector and bulb contacts. If the lens is cracked or the seal fails, moisture can enter and cause intermittent lighting or a short circuit. When replacing this lamp, verify that the mounting bolts seat fully in the bracket holes and that the wiring harness connector is clean and free of corrosion.
