Painless Wiring Courtesy Light Kits: Interior Lighting Done Right

When building or restoring a street rod, muscle car, or custom kit car, interior lighting is one of those finishing details that separates a truly polished build from an unfinished one. Painless Wiring — long recognized as a leader in automotive electrical products — brings that same philosophy of complete, well-engineered solutions to the courtesy light category. Rather than leaving builders to track down individual components, Painless bundles everything needed for a clean, functional installation into purpose-built kits.

What's in a Painless Courtesy Light Kit?

Painless offers two primary courtesy light kit configurations, each designed to address different installation scenarios:

• Universal Courtesy Light Kit (Part No. 30710): This universal kit includes wires and light sockets to install courtesy lights inside your vehicle, and the sockets use 67 series bulbs, which are included. It's a straightforward, no-hunt solution that works across a wide range of custom builds.
• GM Courtesy Light Kit with Door Jamb Switches (Part No. 30702): Ideal for any type of street rod, muscle car, or kit car, this kit includes wires, bulbs, light sockets, wiring terminals, and hardware to install courtesy lights inside your vehicle — with grounding door jamb switches featuring 5/16-18 threads also included. The GM-style housing and gray plastic construction make it a natural match for GM-based builds and restorations.

Each kit contains two light socket assemblies designed to mount under the dash for illumination of the front seat floor area of the interior. The white wire attaches to the dome light power line and the black wire connects to the light switch dome light ground terminal or door jamb switch — and by tying both lights together, both will illuminate simultaneously. This kind of clear, straightforward wiring logic is a hallmark of how Painless designs all of its products.

The Painless Engineering Difference

What sets Painless apart in the courtesy light space isn't just what's in the box — it's the engineering philosophy behind it. A wiring harness is, first and foremost, engineering, and at Painless, all harnesses and accessories are designed by real engineers using the latest diagnostic equipment and AutoCAD to ensure consistency in manufacturing and an accurate, easy installation. That same rigor applies to their lighting accessories. Builders don't have to guess at wire gauge, socket compatibility, or switch thread specs — Painless has already worked it out.

Painless Performance is the recognized leader in automotive wiring products, and their courtesy light kits reflect the brand's commitment to giving custom-car enthusiasts complete, confidence-inspiring solutions. Whether you're wiring a first-time build or refreshing a classic, these kits remove the guesswork and deliver a factory-quality result under the dash.

Who Are These Kits For?

Perfectly suited for street rods, muscle cars, and kit cars, Painless courtesy light kits ensure a stylish and functional addition to your ride. If your project vehicle didn't come with interior lighting — or the original wiring has been stripped out during a full restoration — these kits are the cleanest path to a finished interior.
