Backup Lights & Utility Lights for Trucks and Trailers
Backup lights and utility lights for semi-trucks, trailers, and vocational equipment. Backup lights provide the white reverse illumination required by federal regulations (49 CFR 393) on commercial vehicles, while utility lights deliver general-purpose white light wherever it's needed — under a hood, inside a toolbox, along a frame rail, or anywhere else on the vehicle. Both LED and incandescent options are stocked.
Most lights in this category are 12V, with a selection of 24V and multi-voltage units available for mixed-fleet and export applications. Mounting styles are primarily grommet-mount and bracket-mount, with round and oval housings making up the majority of the selection. Brands include Betts, Grote, Peterson, Pro LED, and Truck-Lite.

Frequently Asked Backup & Utility Light Questions:
Are backup lights required on semi-trucks and trailers?
Yes. Federal regulations under 49 CFR 393 require a white backup lamp on buses, trucks, and truck tractors. The lamp must activate automatically when the vehicle is placed in reverse. Trailers are not required to have backup lights, but many operators add them for safety and convenience.
What's the difference between a backup light and a utility light?
A backup light is a dedicated reverse lamp wired to activate when the vehicle is shifted into reverse. A utility light is a general-purpose white light intended for task or area illumination — engine compartments, toolboxes, cargo areas, frame-mounted work areas — and is typically switched independently or wired to a constant or ignition-switched circuit.
What voltage are the lights in this category?
Most are 12V, which covers the majority of North American commercial trucks and trailers. A selection of 24V and multi-voltage units is also available for European-spec equipment, military vehicles, and mixed 12/24V fleet applications.
Can a utility light be used as a backup light?
Only if it's DOT-certified as a backup lamp. A general utility light may not meet the output, beam pattern, or certification requirements for a legally compliant backup lamp. If you need a replacement backup light, look for units specifically listed as backup or reverse lamps with DOT certification.
What does "multi-voltage" mean for truck lights?
A multi-voltage light is designed to operate correctly across a range of input voltages — typically 10–30V DC — making it compatible with both 12V and 24V electrical systems without modification. These are useful for fleets running mixed equipment or for operators who service both North American and European trucks.
