Prepare to be frustrated, as Mercedes did not make this easy. Remove the plastic outer housing located inside the engine compartment. There is a wire clip holding in the headlight bulb. push the top of this clip to the left and release it from the bracket. pinch both sides of the lower part of the clip (below the bulb) to remove them from the clip. Prepare to have your fingers hurt. Putting it back on, reverse the directions. You will probably drop the wire clip several times during the replacement process. The answer above was VERY helpful, however I found that if you disconnect the lamp from the wire harness before trying to remove the clip, it's not hard at all to remove the clip or to replace the clip after changing out the bulb. The passenger side was MUCH more difficult than the drivers side.
