Universal Courtesy Light Kit

The Painless Wiring Universal Courtesy Light Kit is a 12V interior lighting solution designed for vehicle builders, restorers, and enthusiasts who demand clean, professional-grade electrical installations. This kit is particularly useful for those completing custom hot rods, modernizing classic trucks, or upgrading older vehicles' interiors.

The system operates on straightforward mechanical door-switch logic: when a door opens, the switch completes a circuit that energizes the courtesy lights, then automatically extinguishes when the door closes. The compact, lightweight design (0.35 lbs) and minimal footprint (4.7 x 1.7 x 7.4 inches) facilitate installation in tight spaces, though installation may require some basic wiring knowledge.

This courtesy light kit is ideal for restomod builders, custom truck fabricators, and anyone installing modern convenience features in vehicles that originally lacked them. Its universal compatibility makes it suitable for most vehicles, enhancing safety and convenience with automatic illumination when doors are opened.
