Upgrade Your Vehicle Safety with the Flange-Mounted Truck-Lite 10251R 10 Series 2.5" Red Round LED Marker Clearance Light

The Truck-Lite 10251R (10 Series) is a top-tier, 2.5-inch round red LED marker and clearance light integrated into a permanent gray polycarbonate flange mount. This specialized flange design allows for direct, flush surface mounting to your vehicle or trailer body, eliminating the need for separate rubber grommets.
Built around a high-efficiency 2-diode LED configuration, this red lamp draws an incredibly low current (only 0.03 Amp major), reducing strain on your alternator and leaving more power available for other critical electrical systems. Equipped with Truck-Lite’s legendary Fit 'N Forget M/C system, the light features completely encapsulated internal circuitry that eliminates terminal corrosion and filament wear. Whether managing a vocational fleet or an over-the-road semi-trailer, the 10251R delivers maximum uptime and zero-maintenance operation.
