LED Dimmer Knob - Dim up to 6 Amps of 12V LEDs - Easily mount to a panel

(3 reviews)

Smooth dimming at your fingertips.

Looking for waterproof dimmer knob? We now offer a Waterproof LED Dimmer Knob.

Turn the knob all the way to the left and it will "click" off. Turn the knob clockwise and the brightness gradually increases from 0% to 100%. The best benefit for you: this 12 volt LED dimmer easily mounts to a panel. So all the electronics are hidden away, and you're left with just a tiny knob.

How to mount:
Just pull the pressure-fitted knob straight off, loosen the washer/nut, and attach to a hole drilled in a panel (about 10mm, or 3/8").

Wiring is simple:
Hook up your 12V + and - to the "IN" port, and then your LEDs to the "OUT" port.

Boom! Quick, easy, reliable dimming in one compact piece of next generation solid-state LED electronics.

If you're up for some hacking, and need to fit this in a tight space, you could even de-solder the knob (which is a variable resistor / potentiometer) from the board, attach new wires, and mount it remotely.

LED Dimming Switch Knob

New! You now get two knobs: a black & a silver.
You get both for free in the package, so you can
just pop one off and change the style.

Please note, this will work best on a wired power source rather than a small battery. And of course it will work fine on your car battery too, since that is constantly charged by your alternator.

It won't work on a small 23a sized battery (not enough amperage). It will work for just about 45 minutes on a 9v battery, or an 8xAA battery pack (still not enough amperage for long term use).

As with pretty much all dimmer switches, the ground side is switched rather than the positive side. So you must hookup the output ground wire to your LEDs.

Zoom in size spec

Below is a quick video showing how to hook up your wires. If you find that your LED lights are not dimming, nor turning off, it doesn't mean the dimmer is defective. It just means you've wired something incorrectly. Please go back, double, and triple check that you're wiring it according to the above diagram / below video.

Customer questions & answers

Question:

I used sequential switchback (white / yellow) LED strips and placed them in my door mirrors as running lights and turn signals (not a factory option for my car). The driver has 4 inputs, 2 switched power supplies (running lights and turn signals), constant power and ground but, only 3 outputs, red, blue and black that go to the strip. The white running light LEDs are too bright at night.

1) How would I add this dimmer to the running lights (white) only

2) Would I need 2 dimmers, one for each side, or could I control both left and right with a single unit?

Answer:

If you wire the dimmer knob to a power source then isolate the hot and ground for the running lights you can dim those only. Whatever is attached to the dimmer will be effected so you can wire both sides to the same dimmer.

Question:

Can this be installed under the hood of a pickup near the fuse box to dim an LED grill logo light. Instead of running wires into the cab. Just wondering if under the hood would be out of the weather enough to protect it. Does it run very hot when dimming an led light.

Answer:

It does not run hot. This one isn't waterproof and shouldn't be installed under your hood.

We have a waterproof LED dimmer that will work under your hood.

Question:

can this dimmer switch be used with the your fade in/ fade out switch

Answer:

Not really, when using an external dimmer knob the fade is choppy and the bulb does not give a steady light.

Works Well for LED Instrument Lighting

Christopher Mullet from Fort Worth, TX

I converted my car's weak instrument lighting to brighter LEDs and replaced the old rheostat with this switch. I was able to use the car's original knob on the splined shaft so it still has the original look from the front side. Works great!

Works great.

Jared Sasser from Chipley, FL

The Dimmer Knob works great but does have one flaw. The threads are plastic and the nut is metal and when I pressed the knob on the dimmer switch it stripped the threads on the switch. That's why I'm giving it a 3 star. Other than that it works perfect.

Top quality in a small package

Mark from New York, NY

This was the smallest LED dimmer I could find and it works just as well if not better than others I have tried. I used it with strip lights with no flickering! Will order more.
