The following diagram is for a PWM dimmer using a potentiometer (P1).
This I imagine would be the dimmer circuit for the knob style dimmer (the knob is basically P1).
I just realized after thinking about this some more that the above circuit is actually integrated INTO the Soltice Prime unit itself. I went and took another look at the product photos on the VisionX site and noticed that there is a little green wire sticking out of the new Soltice Primes that is not there on the Soltice Solos.
I believe that the green wire, if driven to an input voltage will control the output of the light. In this case, it seems obvious that having the green wire open signals full light output, driving it with an input voltage will cause the LED to modify it's pulse-width automatically.
This is really good news (assuming I got ANY of this correct - left my EE chops behind about 10 years ago) because it means that you could theoretically achieve the dimming function with a simple fixed resistor.
For example, the green wire:
1. Open=full LED output
2. Driven to 12V = no LED output
3. Driven to say 6V = 50% LED output (usually not linear, but you get the idea).
All you need to do is hook up the high beam switch so that when activated it channels the 12V through the proper resistor and voila, you get the % dim you are looking for. Easy peasy.
My new bet is that the dimmers that are sold through VisionX require 12V input and are nothing more than a potentiometer (dial knob) or two resistors on a switch (50/100 fixed).
