How to Remove a BMW Fog Light
1. Disconnect the ground wire from the BMW's battery. The ground wire is the (usually black) wire that connects the battery to the frame of the vehicle.
2. Locate the fog light access openings. The openings can be found at the upper inside corner of the fog light.
3. Insert the screwdriver into the access opening and pry open the spring-loaded fog light detaining clips. Pushing forward (toward the front of the BMW) will release the clips. The fog light will swing forward along a hinge at the side of the fog light opposite the detaining clips.
4. Pull the fog lights out and away from the hinged side.
