Hi Guys,
I am in the middle of battery powering my Bachmann Railtruck. I have decided to scrap the Bachmann circuit board and so will need to protect the led headlights and tailight. I know I need to reduce the voltage to the Leds but have no idea what to use or what size. Resistor? Diode? Do I wire all three in series or parrallel?
There was some kind of LED primer posted but searching on Led just doesn't work. Any help from you electronics experts will be appreciated!!
