There are three screws (two on the top on bottom) holding the big plastic cap on the HID assembly. You would have to take those three screws out, unhook the plastic clip holding the rubber seal leading to this cap, move the plastic cap off of the back of the HID assembly, unscrew a plastic ring and then take the bulb out.
