Cheers guys.
@Jamaican, This, of course, is just 1 LED from the bread-board. I'm thinking I'll use 2 LEDs for each nacelle. So, probably alot brighter down the Bussard collector end.
@Grendels, personally hope I don't have to do this again anytime soon. The only really tricky bit was blocking the light from the impulse engines and to a lesser extent, making sure it was around all the seams. A coat of black paint before hand might have helped, but I hate gluing with that.
