I've been checking out how others have done the lighting for their ships. Most likely I will be incorporating the standards from what I have seen on the lighting for the nacelles. The saucer and main body of the ship however will be a new approach. I've been working with LEDs, breadboards, resistors, etc... to get in a direction I like. adafruit.com has some options that I will be trying out.
