Truck-Lite 10389Y 10 Series 2.5" Yellow Round Low-Profile 8-Diode LED Flange Mount Marker Clearance Light
Permanent Surface Protection and Slim-Line Visibility: Truck-Lite 10389Y 10 Series 2.5" Yellow Round Low-Profile 8-Diode LED Flange Mount Marker Clearance Light
When outfitting commercial semi-trailers, box trucks, and heavy-duty equipment, surface mounting requires ultimate structural security alongside a tight, low-profile fit. The Truck-Lite 10389Y (10 Series) is a heavy-duty, 2.5-inch round yellow (amber) LED marker and clearance lamp integrated seamlessly into a permanent gray polycarbonate flange mount. This built-in flange allows for clean, direct, screw-down surface installation to your vehicle paneling, completely removing the need for separate open-back rubber grommets.
The 10389Y stands out with its engineered low-profile housing configuration. Measuring a shallow 1.06 inches in depth, this slim-line lamp hugs your trailer paneling tightly, minimizing the risk of expensive impact damage from low-hanging branches, tight loading docks, or side-swipes. Packed with an advanced 8-diode LED array, it projects intense, uniform amber lighting. Because of its elite SAE PC compliance rating, this versatile lamp functions simultaneously as both a side marker light and a clearance light when properly positioned at a 45-degree trailer corner angle. Outfitted with Truck-Lite's signature Fit 'N Forget M/C (Moisture/Corrosion-Proof) connection system and 100% encapsulated electronics, this 12V combination lamp provides an exceptionally low-maintenance solution designed to completely stop terminal rot and environmental moisture failure.
