Betts HD 50 56 57 60 Marker/Clearance and Aux Light
The Betts HD 50 56 57 60 Marker/Clearance and Aux Light uses a single red LED diode to create crisp, visible illumination for heavy-duty vehicles. Its multi-volt design supports varied electrical systems, allowing it to function across mixed-age fleets without additional conversion. The low-draw LED helps reduce electrical strain while still producing a bright signal signature for marker, clearance, or auxiliary use. Weather exposure is handled well by the sealed construction, keeping road moisture away from the diode and internal contacts. If you’re outfitting commercial trailers, the Betts HD 510021 is one of the best tools for maintaining strong visual signaling across long routes.
