I just put a new digitrax basic decoder in an sw7. I know evans designs has them, but what size do I need. I guess they are already rigged with all necessary things and wiring. Is the daylight one better for newer diesels?
I prefer the 3 mm. I’ve used them in Athearn, Walthers, and Bachmann engines. I prefer the warm white. (I think the cool white might work better on modern day engines.) Make sure to get the 7-19 volt leds. Super easy to install because you don’t have to worry about polarity...cheers
