Tardis Interior: Animating Track Lights

clark16

So I've been cutting my teeth in 3ds Max by building the Series 7b Tardis interior. I've got most the pieces together and now I've started animating it. The main problem I'm having is with the lights on the top walls. In the show they light up in sequence like lights on a runway. Does anyone have an idea how I would do this? I appreciate any suggestions. Thanks!
