Struggled to find this anywhere so thought i would just say, if you dont have HID's on your is200 then do it.
The kit was fitted in under 20 minutes and im no mechanic or even a keen diy'er!
Bulb out, plug in HID's mount ballast with cable ties and your done. OK so im not as neat as some people but the ballasts are secure.
Above all that the kit was £48 delivered from HIDS4u (35w slim digital ballast)
Im a very happy bunny
