Ensure your trailer or vocational truck remains visible and DOT-compliant with the 4 Inch Round Stop Tail Light by Automann. This industry-standard S/T/T (Stop/Turn/Tail) lamp is engineered for rugged reliability and universal application. Whether you are outfitting the driver side or the passenger side, this lamp provides high-intensity signaling for braking, turning, and nighttime running, keeping you safe and legal on the road.

Sealed Performance: The 4 Inch Round Stop Tail Light Advantage

The 4 Inch Round Stop Tail Light (Automann Part # 571.LG40R) features a sonically sealed polycarbonate lens that effectively prevents moisture, dust, and road salt from entering the housing. Inside, a heavy-duty incandescent bulb is designed to withstand the high-vibration environment of long-haul trucking. Note: The back of the unit includes an integrated PL3 connector for a simple "plug-and-play" installation, making it one of the easiest components to service in the field.

As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize lighting solutions that meet strict safety regulations. This 4 Inch Round Stop Tail Light is a direct professional-grade replacement for Truck-lite 40202R, Peterson 426R, and Grote 52772. Since both the driver and passenger side lights are often exposed to the same environmental wear, we recommend replacing them in pairs to ensure consistent brightness and signaling across your rear impact guard or light box.
