First take off the wiring harness connected to the bulb. Remember how you took it off so you can put it back on the same way. Then there is a retainer clip shaped like a "v". At the point of that "v", there is a hook holding it in place. Free the retainer clip from the hook and the bulb will come out. The bulb can sit in the hole in one specific orientation. Put the new bulb in. Replace clip. Replace wiring harness. Pau ("finished" in Hawaiian).
