I have a pair of D2S Philips 6000k HID bulbs sitting in my garage from my previous car.

Has anyone changed their HID bulbs? Any DIY around? Do I have the right bulbs?

I have and it's pretty simple
This should help

Same install for 07's?

you have to put it in the oven to take the bulbs out???

No, it's to remove the amber reflector

Come on, I see some signatures with 6000k HID bulbs installed.
