Smooth dimming at your fingertips.
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.
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.
LED Dimmer Knob - Dim up to 6 Amps of 12V LEDs - Easily mount to a panel
LED Dimmer Knob Technical InfoMode of Operation: Continuously variable, pulse width modulation (PWM)
Supply (Input) Voltage: 8 to 20VDC working voltage, up to 30VDC momentary
Output Voltage Range: From zero VDC to supply voltage

Ambient Temp Range: minus 40F (-40C) to 115F (46C)
Standby Current Draw: 3mA (when turned down to 0% "Off")
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.
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.
