Truck-Lite 1101A – Signal-Stat Series, "The Guardian" Incandescent, Yellow Rectangular, 1-Bulb, Marker Clearance Light (PC, Silver Steel 4-Screw Housing, Hardwired, 12V)
Shield your fleet's exterior lighting from punishing roadside abuse with the heavy-duty Truck-Lite 1101A Signal-Stat "The Guardian" Rectangular Marker Clearance Light. Engineered explicitly for commercial trucks, trailers, and vocational vehicles, this 12V incandescent clearance light features a built-in "deflector" design. Its heavy-gauge silver steel housing forms an armored guard around the lens to physically deflect tree branches, loading dock impacts, and flying road debris, ensuring your vehicle stays lit and compliant.
Internally, the 1101A is designed to handle thousands of road miles. It utilizes a field-proven, single-bulb incandescent system cushioned by an integrated internal pressure pad. This specialized pad absorbs heavy road vibrations—significantly extending bulb life—while tightly sealing the high-impact yellow polycarbonate lens against dust, moisture, and road salt. When service is eventually required, maintenance is effortless thanks to a "Quick-Click" lens mechanism that lets you swap bulbs in seconds without removing the heavy-duty housing.
