I got those dimmers from superbright too, Keith. Just use it to interrupt the ground side of the LED unless you have the kind of LEDs that are integrated into the bayonet base. If you cannot isolate the ground side from the chassis ground it becomes much more expensive, as the PWM dimmer for the positive side does not seem to be around for less than $40 last time I looked. I got to the point of looking in my books from college to design my own circuit, but life intervened and the project got sidelined. I really need one for my LED dash and gauge lights, and the gauges are common-grounded inside the sealed unit, so I cannot get to the LED and disconnect the ground side. I also am reluctant to try and isolate all the instrument lights that I put the 194 LED bulbs in. If I find one for the right price I'll PM you.
