Lighting "Wave"

Hey guys
So I’m looking at creating a circle of lights which will erun in a wave pattern round a circular room. So one will light up, then the next will illuminate shortly before the first goes out, and so on.

I was pondering making a point light and having it move around in a big circle outside pieces of clear geometry, but then thought maybe having many emissives and setting their intensity on or off would be better.

Which of these would anyone consider best? And any idea how i’d go about making the lights “trail” (have 2 or 3 active at once with a new one lighting as the last one dims)?
