hi, if it it is any use to someone i bought some 21000[candle power?] 3mm white leds and the resistors for 15volt , to suit my power supply, u solder the resister to one leg of the led then just solder motor power supply + _ to the legs. they work a treat from 10-15 volts and they literally cost pennies for a handfull. mine came from usa and postage was even cheap. i think the resistors were 450? around that mark. john
