I went nuts on my Tyderium, having never done any sort of lighting I referenced The Grail otherwise known as Shep Paine's How to Build Dioramas with its section on lighting. I used his techniques, grain of wheat bulbs, and minimaglight bulbs with a battery pack in a base.
I used the minimags for the engine and instrument baclighting, and color acrylic tube for anticollision beacons, with mag light bulbs in the wings for nav lights.
I learned a lot from doing it and it was a great experiment....not to be repeated! :D
I would go with the lightsheet, I think you will get more even results overall and use LED's and a blinking chip from over at starship modeler for nav lights and such.
