In fitting a Silent Running  decoder in a diesel loco,how should the front and rear led lights be wired,when this decoder supports both lights.Blue  and white for the front,and blue and yellow for the rear ?.

They should wired exactly like you said. Just include a 1k, 1/4 watt resistor in series with the yellow lead and the white lead. That will allow about 9 ma current for each LED. Not a big deal.

RichG, Thanks ,I think I created a short circuit recently and blew a decoder. I  I put a resistor on the blue wire. However that is the past,I will stick to your  advice and put resistors only on the white and yellow wires.
