How to Replace a Mercedes E500 Headlight

1. Open the hood. Squeeze the connector tabs and pull the headlight connector off of the back of the headlight.
2. Pull the dust cover off of the back of the headlight housing with your fingers and set it aside.
3. Grab the headlight by the base and twist it counterclockwise. This will unlock it from the housing.
4. Pull the old headlight out and put the new one in, making sure that you don't touch the glass bulb in the process. Touching the bulb can shorten the bulb's life. Installation is the reverse of removal.
