Truck-Lite 3693W Signal-Stat Clear 4" Round Incandescent Back-Up Light (12V, 1-Bulb, Chrome Flange Mount, Hardwired, Stripped End)

The Truck-Lite 3693W (Signal-Stat Series) is a heavy-duty, 4-inch round incandescent back-up light built to deliver reliable rear-facing illumination for commercial trucks, vans, and utility trailers. Featuring a premium zinc die-cast housing with a brilliant chrome flange finish, this surface-mount utility light adds a polished look while standing up to tough road conditions. Its shallow, narrow-depth design makes it the perfect choice for vehicles with limited space behind the mounting surface.

Space-Saving Profile with Premium Styling

The Truck-Lite 3693W Signal-Stat back-up light is engineered to offer maximum visibility without requiring significant installation clearance. Featuring a shallow recess depth, this light is ideal for custom truck bodies, commercial delivery vans, and specialized trailers with limited clearance behind the mounting panel. The integrated zinc die-cast chrome flange provides a high-end, classic aesthetic while creating a robust seal against the vehicle.

Maximum Durability and Field Serviceability

Designed with long-term maintenance in mind, the 3693W features a three-screw acrylic/polycarbonate lens assembly. Rather than throwing away the entire light when a bulb burns out, you can quickly and easily replace the internal #1156 incandescent bulb by removing the three retaining screws—saving your fleet time and money.

Reliable, Retrofit-Ready Wiring

This 12V back-up light comes hardwired with an 18-gauge stripped wire lead, making retrofits over existing truck wiring effortless. Whether you are replacing a worn-out legacy back-up lamp or upgrading your fleet's rear-end layout, the Truck-Lite 3693W provides a heavy-duty, DOT-compliant safety solution that keeps you visible and safe.
