How to Replace a Fog Light on a BMW

Updated July 20, 2017

Replacing a fog light on a BMW is a surprisingly simple task. With just a screwdriver, you can remove and install fog lights in a matter of minutes. For any BMW, be sure to get fog lights that have clear lenses that are SAE-approved with an OE replacement. Fog lights are usually sold individually, but if replacing fog lights is part of routine maintenance, you may wish to replace both at the same time.

Disconnect the ground wire from the battery of your BMW. The ground wire is the black wire connecting the battery to the frame of your BMW.

Find the access openings for your fog light. These are located at the upper-right inside corner of your fog light.

Open the clips in the access opening with a screwdriver. These spring-loaded detaining clips should release if you push forward on them with the screwdriver. The fog light will fall forward along the side hinge, which on the opposite side of the detaining clips.

Pull out the fog light, bringing it away from the hinge.

Remove the protective covering on your new lens. Submerge the new light in hot water to peel the protective film off of the new light.

Add a thin bead of sealant around the new fog light lens.

Insert the fog light along the hinge of the access opening.

Press the fog light into the access opening for several minutes to allow the sealant to firm, gluing the light in place.

Reconnect the ground wire to the battery and the body of your BMW.
