Weatherproof

Built for outside

Weatherproof (IP54), so it can live on a tailgate, a trailer or a rack, not just inside.

The button takes a firm press, so bumps won't easily flip it.
Switches sit side by side for a clean switch bank.
Mount it where you can reach it, even if the light is up high.

“I chose the analog rotory dial dimmer switch over the touch version mostly just for the tactile-ness of it. It functions amazing and a must have for the kingpin lighting set up, unless you like being blinded all the time lol. Also makes ease of acess to turn on the lights on and off much easier if your light is mounted high. Highly reccomend to buy, because it compliments the kingpin lights so well.”

Full product description

A weatherproof (IP54) dimmer for inside or outside. Click the button to turn your lights on or off, and turn the dial to set the brightness. It stays at your last brightness.

The button takes a firm press with a solid click, so bumps won't easily turn your lights on or off.

It works with every Kingpin light, F-Series and V-Series, mixed is fine. Each switch handles up to 3 amps: two 40" lights, four 28" lights, eight F-Series 12" lights, or six V-Series 12" lights. On F-Series lights, the red/white button still works.

It mounts on any flat surface with the included die-cut 3M VHB tape. Size: 2.7" × 15/16" × 1", with about 6" of 20 AWG lead on each end.

Install tip: power comes in at the knob end, and the crowns point toward the lights.

Questions

Good questions, short answers

The knob end. Power from the battery goes in at the knob end, and the lights connect at the button end, where the crowns point. Wired backwards, it only turns on and off and won't dim. Just swap the ends.

Up to 3 amps of lights: 2× 40", 4× F-28, 8× F-12 or 6× V-12. You can mix F- and V-Series, just add up the amps: F-40 1.1, F-28 0.7, F-12 0.3, V-40 1.4, V-12 0.5.

It's not likely. The button takes a good, firm press, so a bump won't easily turn the lights on or off. You'll hear a solid mechanical click when you press it.

Yes. The dial stays where you left it, so the lights come back on at the same brightness.

No. On F-Series lights, color is set on the light. Turn the light on and pick white or red with its buttons. The dimmer then turns it on, off and dims it in that color. To switch colors, press the button on the light.

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

About 6" on each end, 20 AWG, with bare wire ends, ready to connect. Add the Power Cable to reach farther.

Rotary: weatherproof (IP54), a firm click button, and a dial you can feel. Touch: small and flat, tap to turn on, hold to dim, for inside spots only (not weatherproof).

Any 12V DC source works, like a power station's 12V outlet. Most USB ports are 5V, so they won't run the light. Some higher-power USB ports may work, but we don't recommend it.

2 years from the ship date. Send a photo or video of the install and the issue, and we'll replace it or credit you.
