Mesaflyer,
The Imperial Valley Radio Control Association awards Bat Wings when you complete your first night flight.
Member Jim P built a plane with tranparent covering with a lot of peanut lights in it . It was awesome to watch.
He did this before the proliferation of LEDs which may be a better way to go.
You might get ahold of Archie at El Centro Hobby, he is a good builder and he and Jim P are good friends.
Good Luck,
