The light

Bright, not blinding

Every Kingpin light has a thick, diffused lens. It spreads the light out into one smooth, even glow, and protects the light from hard knocks.

  • No bright hot spots. The whole bar glows evenly.
  • No harsh glare, so it's comfortable to look at, even up close.
  • Soft, even light on your gear, with fewer hard shadows.

Full product description

Need a single dual-color rotating 40" light and dimmer switch to control it?  Already have 12-volt power available? This is the package for you.

This low profile 40 inch light kit rotates 360-degrees and can swap between bright white and red night vision with a click. Set the vibe as needed with the included Rotary Dimmer Switch. Connect everything with matching Power Cable. 

This the perfect light kit for truck tailgates, SUV hatches and Jeep rear windows, and so much more.

The Kit Includes:

(1x) F-Series 40" Dual-color red or white light

(1x) Set of Search Mounts to provide 360-degree rotation

(1x) Rotary Dimmer Switch 

(1x) Wire spool to connect everything 

Need to connect power to a 12-volt battery?

Just add our Power Supply Kit. Connect it to your battery, route the wires along your chassis, mount your lights and switches, connect everything up and you are ready to rip! 

Note: You'll need to cut, strip, and connect a few wires to complete the installation. 

Questions

Good questions, short answers

No. Use your own fused 12V feed, or add the Power Supply Kit (from the battery) or the AC Power Supply (from an outlet or power station).

Wire strippers, connectors for 20 AWG wire, and wire routing supplies. They aren't in the kit.

Yes. Each dimmer runs up to 3 amps: 2× 40", 4× 28", 8× F-12 or 6× V-12. Add up the amps in each zone.

No. A thick, diffused lens spreads the light evenly, so there are no bright hot spots and no harsh glare. It's easy to work under and easy to be around at camp.

The whole kit draws 1.1 amps at full brightness.

Yes. It's weatherproof (IP54): dust-protected and splash-proof from any direction. Don't submerge it.
