Permanent Surface Protection and Wide-Angle Visibility: Truck-Lite 10279Y 10 Series 2.5" Yellow Round High-Profile 8-Diode LED Flange Mount Marker Clearance Light
When outfitting commercial semi-trailers, box trucks, and heavy-duty equipment, surface mounting requires ultimate security alongside uncompromised side-angle visibility. The Truck-Lite 10279Y (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 10279Y stands out with its engineered high-profile lens design packed with an advanced 8-diode LED array. This extended dome geometry projects intense, bright amber light outward and horizontally, minimizing devastating blind spots for adjacent highway traffic. Because of its elite 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 an industry-standard PL-10 plug connection and 100% encapsulated electronics, this 12V combination lamp provides an exceptionally low-maintenance solution designed to slash fleet replacement costs.
