Truck-Lite 40809 40 Series Left Hand LED/Incandescent S/T/T Light Module Box with Side Marker & Back-Up - 12V Black PVC Trim
Upgrade your straight truck’s rear signaling system with the high-performance Truck-Lite 40809 40 Series LED/Incandescent Left Hand Combination Light Module. Built for driver-side (LH) fleet applications, this heavy-duty 4-lamp cluster combines high-efficiency LED elements for Stop/Turn/Tail functions alongside traditional incandescent back-up and side marker clearance lighting. Enclosed in a rugged steel module box with a sleek black PVC trim face, this 12V assembly provides an ultimate, weather-sealed signaling solution for commercial transportation.
Bridge the gap between reliability and value with the hybrid Truck-Lite 40809 40 Series Left-Hand Combination Light Module. Highly favored as a premium upgrade or direct replacement for straight trucks, vocational vehicle fleets, and specialty delivery bodies (including USPS configurations), this all-in-one rear lighting cluster consolidates braking, turning, nighttime tail tracking, reverse backup, and side-clearance tracking into a single, pre-wired housing.
The structural foundation of this module features a heavy-gauge steel enclosure box engineered to safeguard internal 14-gauge wiring from aggressive road salt, moisture, and flying debris. The exterior trim face is crafted from impact-resistant black PVC for a professional flush look against the vehicle body panel. Inside the housing, the unit utilizes advanced hybrid technology across four separate lamps: high-visibility LEDs for the critical red Stop/Turn/Tail (S/T/T) functions to guarantee immediate signaling illumination, paired with long-lasting incandescent modules for the clear reverse back-up and yellow (amber) side marker clearance lights.
Installation is streamlined via an integrated 5-wire harness layout terminating in a straight PL-2 plug connector paired with a secure ring terminal grounding configuration.
