For example, if the voltage is 3v, and current is 20mA, you need to find a resistor to get that current. So, 12v - 3v = 9v across the resistor 9v/20mA = 450ohm, 1/4w resistor in series Solder it all up and cover it hot glue to keep from shorting If you post the actual numbers I can figure out the resistor you'll need. -Dave If you ever find yourself in a fair fight, your tactics suck.
