If you go to a walmart and go to the fishing/hunting place you should see these glow stick looking things have have a light bulb in them and has a switch to cut them on and off. It is about the same size of a regular size glow stick. They have a red, green, and white one. For the inside wing lights I am not sure what kind of bulbs are in there. We made our on strand of lights.
I will find out if you want me to on what type of bulbs they are.
