Maintain roadside safety and legal compliance with the Truck-Lite 5056D Signal-Stat® Driver-Side LED Combination Box Light.

Equipped with 15 solid-state LEDs set behind a red and clear acrylic lens and black ABS housing, the Truck-Lite 5056D handles road shock, chassis vibration, and outdoor weather exposure without failing due to broken filaments.
The Truck-Lite 5056D simplifies your trailer's roadside lighting setup by integrating six essential functions into a single unit: stop light, turn signal, tail light, side marker, clearance marker, rear reflex reflector, and license plate lighting. The bottom clear window directs crisp light downward onto your license plate to keep your setup completely legal under federal regulations.
Designed for quick installation and replacement, this light features a 3-wire hardwired lead with stripped ends to connect directly to your trailer’s 12V harness. Compliant with FMVSS 108 standards (P2, T, A, I, L, S rated), its universal 2-stud mounting setup fits standard trailer brackets.
