Unlike most vehicles that have side marker lamps on the turn signal assembly, the E320 has a separate assembly solely for its side marker lamps. To replace the lamps, the entire assembly will have to be removed from the vehicle. It's actually a simple job that requires only a replacement bulb. The E320 uses a 5W bulb, which can be purchased at most automotive parts suppliers.

    Turn the headlight switch to the off position and put on the gloves.

  2. 2

    Slide the side marker lamp unit toward the front of the vehicle. Remove the rear end of the unit first.

  3. 3

    Twist the bulb socket counterclockwise and remove it. Pull the old bulb out of the socket and push in a new one. Reinstall the socket by pushing it into the assembly and twisting it clockwise.

  4. 4

    Reinstall the lamp by placing the rear end into the bumper and snapping the left front end into place.
