Universal Courtesy Light Kit

The Painless Wiring Universal Courtesy Light Kit is a 12V interior lighting solution designed for vehicle customization and retrofit applications. This courtesy light kit features a white lens assembly housed in a gray plastic enclosure, delivering clean, ambient illumination for cabin interiors, truck beds, trailers, and utility vehicle compartments. The kit format provides all necessary components for straightforward installation without requiring specialized wiring expertise.

At 12 volts, this courtesy light operates on standard vehicle electrical systems found in most cars, trucks, RVs, and utility trailers. The white lens provides neutral, functional illumination suited to general-purpose interior lighting. The gray plastic housing offers corrosion resistance compared to uncoated metal alternatives, making it practical for environments with moisture exposure or temperature cycling. The compact footprint—measuring 4.7 x 1.7 x 7.4 inches—fits tight mounting spaces common in door panels, overhead consoles, and cargo areas.

This kit is ideal for builders, restoration shops, and vehicle owners performing electrical upgrades or adding interior lighting to custom builds. OEM replacement applications and aftermarket lighting retrofits represent common use cases. The kit approach eliminates sourcing individual components separately, reducing installation time and ensuring parts compatibility. Painless Wiring's reputation in automotive electrical systems provides confidence in component quality and safety ratings suitable for mobile applications.

Vehicle courtesy lights represent a standard interior feature across automotive applications. Interior lighting kits address both functional visibility and cabin ambiance, particularly valuable in work vehicles, campers, classic car restorations, and custom truck builds where original lighting is absent or inadequate. This kit's universal design accommodates multiple vehicle types and mounting orientations.
