3760010-H0100 Side Marker Lamp is a side position warning light mounted on the side skirt or fender of DFL heavy truck. It emits amber light to mark the vehicle’s lateral outline, reminding surrounding drivers of the truck’s overall width during dusk, foggy weather and night travel. This aftermarket replacement lamp fixes dim output, no light trigger and water condensation issues caused by cracked lens, internal LED burnout and corroded pin terminals of old marker lamps. Clear side marking lowers side swipe risks and helps fleets meet road lighting regulatory requirements for highway freight operations.
Product Advantages Textured PC lens delivers uniform light diffusion and blocks ultraviolet radiation to slow yellowing. Compact integrated LED module consumes low power and maintains steady brightness under vibration. Sealed housing design prevents rainwater and road grime from invading the internal circuit. Every lamp is checked for illumination continuity and waterproof performance before packing, plug-in connector matches original harness directly for quick fitting.
