Truck-Lite 4018 – Signal-Stat Right Hand (RH) Combination Box Light, Incandescent, Red/Clear Polycarbonate Lens

The Truck-Lite 4018 Signal-Stat Combo Box Light is a high-performance, multi-function lighting assembly engineered for the Right Hand (Passenger Side) of medium and heavy-duty vehicles. This 5" x 6" rectangular lamp serves as a direct OEM-quality replacement for GM medium and heavy-duty trucks manufactured between 1972 and 1985.

Constructed with a rugged red and clear polycarbonate lens, this all-in-one unit integrates stop, tail, turn, backup, and license plate lighting into a single, compact housing. The black polycarbonate integral housing is built for longevity and features a 3-bolt stud mount for a secure, permanent installation on a variety of chassis and vocational bodies.

Designed for serviceability and durability, the 4018 features a junction box cover to shield internal wiring from the elements. The screw terminal connections provide a robust electrical interface that resists loosening under heavy road vibration. As a bulb-replaceable unit, it allows for cost-effective maintenance, making it the ideal choice for keeping classic commercial fleets safely on the road.
