How to Remove the Head Lamp Lenses on a Mercedes CLK
1. Look into the hood of your car and locate the top of the head lamp.
2. Remove the electrical connector that is located at the back of the head lamp. To do this, grab the back of the lamp and wiggle it until it pulls loose.
3. Locate and grab the bulb holder that is located at the back of the housing for the lamp. Turn it halfway in a counter clockwise direction until you feel that you can pull it out of the housing.
4. Turn the bulb counter clockwise approximately a quarter to a half turn and pull it from the holder.
5. Lever a screwdriver into the bottom of the two plastic clips that you will see are holding the lens in. Be very careful on this step. The headlight lens can crack very easily if you force it out of its clips. Once you have the screwdriver pushing the clips out, you can gently pull the lens up and out.
