will any pwm work to din 12v led lights? been looking around there's light specific and motor.

 

Yeah pretty much yes. I'm running some LED strip lights now. They take 12V on one line. I can turn on any color by grounding the R G or B (even the extra White line these have) by grounding that color pin.

I have a micro controller putting out a PWM signal driving the gate of a logic level MOSFET, drain to the LEDs, source to ground. I have them running at a pretty high frequency (5K I believe) as I can see most flashy things but anything above 100Hz should work for most people.

 

What is "a 12 volt LED Light" ?
You need a schematic drawing and Voltage and Current Specifications.

I have a similar 12 volt LED light strip. It has different colors of LEDs, red, blue, and green and each positive has a current limiting resistor while the negative from each color is a separate trace. Three diodes in each little set, and tghe whole thing is about 2 feet long. So much for the circuit diagram. None available but now you have a description.
