Truck-Lite 10 Series - Yellow Round 2 Diode LED Marker Clearance Light, P2, Gray Polycarbonate Flange Mount, Fit 'N Forget M/C, 12V
Secure Your Fleet's Visibility with the Flange-Mounted Truck-Lite 10251Y 10 Series 2.5" Yellow Round LED Marker Clearance Light
When choosing exterior marker lights for commercial semi-trucks, trailers, and heavy-duty equipment, surface mounting requires maximum security and permanent protection from road abuse. The Truck-Lite 10251Y (10 Series) is a heavy-duty 2.5-inch round yellow (amber) LED marker and clearance light integrated into a rigid gray polycarbonate flange mount. This specialized surface-mount design allows for direct, screw-down mounting directly to the vehicle exterior, providing a secure installation without the need for separate open-back rubber grommets.
Operating on a low-amperage 12V system, this energy-efficient 2-diode LED lamp draws significantly less current (only 0.08 Amp major) than traditional incandescent lights, which lowers battery drain and frees up vehicle electrical capacity. Equipped with Truck-Lite’s legendary Fit 'N Forget M/C system, this sealed assembly shields vulnerable electronics from the components that plague lesser truck parts. If you need to minimize vehicle downtime and eliminate frequent replacement cycles, the 10251Y is the reliable choice for front and side trailer lighting.
