nice, thanks for the info. Do you happen to know the differences between the 3 kits XD offers? I was hoping they can provide more info on the 3 kits.

 

Sorry can't help you there. I did have the Volt kit on my IS though and it worked well. Installation was a cinch and the bulbs lasted from when I got them in 08 through when I sold the car this year.

I would occasionally have an issue where one of the bulbs wouldn't turn on if I had them set to turn on when the headlights turned on. A quick flip of the switch on/off fixed that right away though. Good luck with your purchase

 

Since the stock HID bulbs are 4300K, any of the 4300K HID kit options would work. Since this is for a vehicle and you need 2 bulbs you would have 2 options; the Xtreme or Volt.

There is 3 main differences between the two:

1) The Xtreme HID kit will come with a relay harness that will power the ballasts directly from the battery whereas the Volt kit relies on the OEM headlight wiring to power the ballasts. The Xtreme harness will ensure that the ballasts always receive a constant 12V as power is being drawn directly from the battery.

2) The Xtreme ballasts will be superior to the Volt ballasts as they use a German processing chip that allows the ballasts to monitor the bulb power requirements on a real time basis. This will extend both bulb and ballast life.

3) The Xtreme kit comes with a 3 year warranty whereas the Volt kit comes with a 2 year warranty.

Hope that helps,
Danny
