Maintain maximum highway visibility and DOT compliance with the heavy-duty Truck-Lite 30503Y Yellow Round Incandescent Marker Clearance Lamp Kit. Part of Truck-Lite's industry-proven 30 Series product group, this multi-functional 2" lighting assembly comes as an all-in-one installation kit. The package contains a premium yellow incandescent lamp, a rugged 30700 black PVC grommet, and a 94902 plug harness, providing everything you need to quickly upgrade or restore your commercial trailer's lighting network.
This kit features a 12V hermetically sealed incandescent bulb engineered with a robust, extended-life filament rated for up to 15,000 hours of reliable service. The lens and housing are molded from high-impact polycarbonate, permanently sealing out moisture, dirt, and road debris to eliminate premature failure and connection corrosion. Serving as a direct replacement for legacy Wabash and Monon trailer configurations, this specific "ABS" version is also fully compliant with FMVSS 108 requirements for ABS malfunction indicator lights on trailer braking systems.
Thanks to its smart optical engineering, the 30503Y carries a dual SAE P2, P3, and PC rating. When installed at a 45-degree angle in compatible mounting brackets or surface flanges, a single lamp legally functions as both a side marker light and a clearance light simultaneously. This clever dual-compliance drops your fleet's total light count, minimizes labor overhead, and cuts replacement part costs.
