Hi All:
Are you thinking about going to "golden white" or white LED's in your locomotives? Not only do you need to add a dropping resistor in series, but a diode too! This protects the LED. I burned out 3 out of 5 of them because of no diode. A diode is like a one way street. Only lets current flow one way. So when the locomotive is in reverse, the diode prevents the reverse voltage to damage the LED.
NOTE:
Most DCC boards has these electronic devices built into them.
