Edge texture with moving light for pathways

[stevet1]

I'm looking at add an edge to some paths which I'd like to be a strip with a light moving along it in waves.
What's the easiest way to do this? Is there an existing animated texture that I could use, or is there an alternative method that would work well? Not looking at add in something too resource intensive as some of the kit we run these maps on are not very high spec.

You're going to have to add a series of dynamic lights which are activated/deactivated using ACS.
