Not off the top of my head.
But, I love Underworld, too (and Underworld II.

).
Kickass babe with guns!!!
Ooo. Here's an idea. After removing the powder and primer from the bullets, make the firing pin area of the casing removable. Unscrewable or just a simple pop-off (with some slight effort of course). That way you can go in and change the small watch/hearing aid battery in each round.
Otherwise, put the electronics in the base of the clip and run the LEDs in series up the back of the clip into each of the bullets. That way you only need one AA or AAA battery hidden in a area of the base of the clip that could be relatively easily changed.
Those are just off the top of my head.
Hope it helps.
Keep it up. I wanna see more while you're doing it/done.
