I have been reading the IFM coaches thread on the other page with interest. I think another benefit of the many smaller suppliers of kits and models is the sheer variety, which led me to carriages that I didn't know anything about. By the kit for the Bredin sides being available I learnt a lot about the history of these carriages .plus having fun building it of course. Anyway, I decided to try to add a light strip , it didn't quite work with only one led but I'll add another. I made up a small battery box that sits under the carriage and holds two small round watch type batteries. The batteries are available these days from the pound shops in packs of 20. Anyway, it was fun.
