Light up hallmark spaceships????

I was watching an ebay auction the other day and I noticed one for the
Enterprise E. It had light up engines and so on. I suppose it hooks to
christmas light strings.

It occurred to me it might be neat to somehow attach it by a short wire to a
battery and have it move across the full thrust table lighted up. I have no
idea if it's feasible though. It would be impractical to connect your ships to
the wall by a christmas light string.

Has anyone done this, or does anyone wish to comment on the feasiblity of it?
I don't know how much it's possible to disassemble the lights so I don't know
how feasible it would be to replace the lights or wiring with other lower
power wiring, if that should be necessary. I'm afraid I wouldn't have the
skills or tools for a project of that magnitude anyway.
