This combination clearance/marker lamp provides both red and white light output from a single housing. The red lens faces rearward for tail or brake indication, while the white lens provides side or rear work-area illumination. The lamp mounts via two M5 threaded fasteners at a fixed hole spacing; the housing is sealed against moisture ingress typical of agricultural environments. When a lamp fails, the loss of rearward visibility compromises the machine's road-going safety marking. Replace the gasket between the lamp base and the mounting surface during reinstallation to maintain the seal.
