They are 100mm OD RGB colorshift halos from AAC, that's the reason the surface mounts LEDs are so big. If I'd stuck with a single color halo I'd have more lights and they'd be in a tighter ring, but since I want to use green as the primary color I have to be able to switch to white for driving, hense the RGB halos. Now, I'm going to try to see if I can set it up so they are green with ignition on (with a relay for constant on for shows) and automatic white when shifted out of park. I'm thinking I'll tap a relay into my shifter harness.
You're also looking at a set that's been painted black then had the paint over the LEDs removed. This is what the stock rings look like (these are the unpainted fog rings)
