Here is the first lighted coaches I did. I had a couple of these "East" shinkasen trains that have the headlights so I added a 3V light to each one and then used connectors to connect one to the next. in the 2nd iteration I chose to just put a 3V button battery (CR2032) in each coach... why? because a 5y/o and 3y/o don't really understand that the connectors aren't meant to act like a whip to swing around the car. at any rate, take a look.
thanks Super for the inspiration!
