This is not going to be a quick job.... to get at the bulb you will have to remove the foglight from the car. Then remove the lens, as shown in the drawing below.
To get the foglamp out, (unless you can somehow reach it from beneath the bumper) the WIS procedure is to remove the front inner fender liner. You will have to remove the relevant front wheel to get at the screws to do this. :thumbsup:
