Truck-Lite 10204R 10 Series Red Round Incandescent Marker Clearance Light – 2.5 in., 1 Bulb, PL-10 Connection (24V)
Ensure your heavy-duty commercial vehicles remain fully compliant, highly visible, and safe on the road with the Truck-Lite 10204R 10 Series Incandescent Red Round Marker Clearance Light. As a critical 24-volt electrical component within the industry-standard Model 10 product family, this 2.5-inch sealed lamp features a heavy-duty single-bulb configuration engineered to deliver a bright, crisp red light. Built specifically to satisfy the strict requirements of 24V commercial fleets, international logistics trailers, military transport, and heavy vocational equipment, this clearance light blends classic incandescent performance with Truck-Lite’s legendary environmental engineering.
The Truck-Lite 10204R is manufactured using a premium, high-impact polycarbonate lens and housing assembly that are permanently sonically sealed together. This robust, single-unit construction eliminates the need for separate gaskets or loose screws, locking out destructive moisture, dust, road salt, and dirt before they can threaten internal components or cause premature shorts. The internal 24V heavy-duty single filament is built for long-haul durability, carrying a 15,000-hour-rated operational lifespan that minimizes maintenance cycles and fleet vehicle downtime. For a quick electrical swap or retrofit, the back of the lamp features a standard industry-style PL-10 plug receptacle that hooks up seamlessly to your existing 2-wire harness. Whether deployed as a rear tracking light, side marker, or corner clearance unit, this 24V red light delivers a tight, vibration-damping fitment when paired with standard 2.5-inch rubber flush-mount grommets or specialized mounting brackets.
