Here are some additional tips for changing the license plate light on a Mercedes CLK:
* You may need to use a flashlight to see the plastic rivets and the bulb socket.
* Be careful not to drop the plastic rivets or the bulb.
* Make sure that the new bulb is properly seated in the socket before you reinsert the license plate lamp assembly.
* If you are changing the bulbs on both sides of the vehicle, be sure to change the left and right bulbs. The bulbs are not interchangeable.
