Fred (nine8six) hasn't said much lately, but hopefully he will have some kits before long. That's definitely the best route to go.
The headlights sold by extreme have fit issues, LEDs that burn out after little use, cheap plastic everywhere and no UV coating on the main lens (a little sun exposure and the plastic main lens will look terrible). The built in projectors are also made of cheap plastic (even the reflectors themselves) and I would consider them a fire hazard. I "repaired" a set for another member and was appalled by the quality (lack thereof) at every step of the disassembly.
