I just changed same bulb on my '95 e320.
using flat blade screw driver CAREFULLY pry the black plastic trim surrounding the shifter handle. if you have an uneven hand then use flat plastic instead of screwdriver. the bulb is at the front (fiewall) of the cavity. use your finger to pull the bulb seat down out of its houseing. two wires lead to the bulb holder, although I don't recommend it I pulled on the wires and the bulb came right out. replace with same wattage bulb to avoid melting plastic in the future. pushing the bulb back in is a little tricky since there is sol little wiggle room for your finders. take your time. let us know if you succeeded.
