I am currently working on an Amtrak P42 Athearn Blue box model, I am to the point of adding a decoder to it. I have a 9 pin wiring harness from Digitrax that will help with the conversion to DCC. The question I have is that I would like to put ditch lights on this model and not sure what size of bulb or led that I will need. The decoder that I want to use is the Digitrax SDH164D sound decoder. Any recommendations? Thanks! Kevin Anderson
