BTW, the plasmas seem to be the way to go -- offering the single, continuous glow of the ring like CCFLs and the brightness of the SMDs. Oracle has the plasma Halos for the 2013-14 GT fog lights but not for the headlights (yet). Here are two links to the halos on headlights and fog lights: Halo headlights Halo fog lights
The plasmas are nice but the LEDs aren't that noticeable.
You also get multiple colors with the LEDs, switch it for street legal, then switch to a red or a blue for fun.
Plasmas are single colors.
