It is a H7 bulb. Stick with one of the major brands ie Philips, Sylvania, Osram.<p>To replace, twist the cover off, counter clockwise. There are no clips that hold the connector to teh bulb. You pull it straight back. Be careful though, often times they are brittle and come apart. once thats off, Push the clips that hold the bulb in towards the front of the car, then lift them out of their retainers. <p>Make sure you note the position of the bulb. There is a tab on it that locates it in the headlight assembly itself. I believe it goes straight up. It is possible to put the bulb in wrong, and it will throw of the beam from the headlight since the bulb will be tilted. Good luck!
