Hello everyone! First post here, and looking for some guidance. I am in my 30's now, and haven't done anything with model railroading since i was a child, which consisted of a simple HO DC EZ track layout on my bedroom floor. Anyways, my love for trains has never diminished, and instead of building a layout, I would like to display some of my locomotives on a small shelf on a wall. Currently I am interested in displaying my Proto 2000 Southern Pacific #6053 E8/E9. I would like to replace the lighting with LED, but still maintain the Mars Light, and maybe add an additional light below the mars light in the glazing which would also light up the number boards. My first issue is, how could I make a display locomotives lights function without DC power? Is there a way to operate the lighting via a battery and a remote control? Secondly, where would i even begin to look to find a mars light LED that would fit my shell? I thank you in advance for your replies and help!
