:agree: But i think it is a 7mmThere is a small door underneath the fog light on the bumper. There is one screw that holds it in place. You will need a small ratchet for it, I think it is 8MM or there abouts. It is hinged. You then reach up in there for access to the light. Small hands help alot as the door is only about 3 to 4 inches square.
