Hello Kevin,
I am currently in the process of building the excellent 1:35 scale MiniArt European Tram Car, and even before seeing your very helpful post on Britmodeller, I was already thinking that I want to have working lighting on this model. I have ordered a couple of LED & Fibre Optic kits from a seller on Ebay, which should be arriving during the next couple of days . . . . . In my head I do have a sort of idea where I might locate the PP3 battery and also thoughts about how to route the wires and the fibre optic tubes, but do you have any previous information about how you went about this yourself?
Please don't go to any trouble over this Kevin, but I would be interested to know how you approached the lighting setup for this tram.
Many thanks,
David Watson
