How to Replace Marker Light in a Mercedes

1. Lie on the ground beside the bumper fascia and reach up under the bumper and locate the back of the amber marker light housing with your hand.
2. Locate the socket directly in the center of the housing and turn it a quarter turn counterclockwise while you pull outward. This releases the bulb socket from the lens housing.
3. Pull the bulb out of the socket and press the new bulb into the socket.
4. Place the socket into the back side of the marker light housing and turn it a quarter turn clockwise to lock it into the housing.
5. Repeat the process on the other side of the Mercedes if that marker light is burned out.
