Default Re: usb lighting

White wire through diode to positive lead of capacitor (negative of cap to ground). Positive lead of capacitor to 12V in of USB reg. 5V output of USB reg. through resistor to anode of LED. Cathode of LED to ground. Throw a switch in there to turn the lights off.

If your spark plug runs off the negative phase of magneto, should work fine.
