Driving around with a headlight bulb missing can affect the operation of the car by limiting visibility. The Volkswagen Passat uses a headlight bulb that is attached to a wiring connector in the back of the headlight assembly. Replacing the headlight will take a matter of minutes as the headlight bulb is easily accessible in the engine compartment. Always replace the bulbs when they go out to ensure optimal visibility.
Determine which headlight is bad by looking at the bulbs while the lights are on. Turn the high beams on to determine if the high beams are functioning.
Turn the car off and take the key out of the ignition. Open the bonnet for access to the back of the headlight assembly.
Unscrew the back of the socket counterclockwise and pull it out of the back of the headlight assembly. Pull the electrical connector off the back of the socket by separating the tabs and pulling away from the connector.
Insert the connector to the new light. The connector will lock in place.
Push into the back of the headlight assembly. Turn clockwise to lock in place.
Turn the headlights on to test that the headlight is working properly. Turn the headlights off and close the bonnet.
The part number for the bulb is H7.
Allow the car to cool down before reaching into the engine compartment.
