When changing a headlamp in a mercedes benz c280 1995. Lift the hood latch on the inside of the car. This is located under the driver side of the car. Release the hoodlatch in the front. Open the hood and behind the headlamp (left or right), Remove the two clamps that hold the back cover onto the light. After this cover is removed, behind the headlight there is a wire behind the light that hold the light in. Squeeze the two wires together and pull them back. This will release the light. Remove the light from the socket. Place the new bulb in the socket. Remember not to touch the bulb with your fingers, this could cause the bulb to break if it gets the oil from your fingers onto the bulb. Once the bulb is replaced, put the wire back in place and replace the back cover of the light.
