When a headlight burns out on your Volkswagen Passat, you should install a new bulb as quickly as possible. Failed headlights reduce your field of vision on the road and make it more difficult for other drivers to see you. Most state laws require that your headlights be functional at all times, so replacing them will also keep you out of trouble with the law. Buy a 1255 headlight bulb at an auto parts store.
Raise the bonnet of your Passat. Use a flat-bladed screwdriver to pry up on the locking tabs around the bulb socket.
Press the retaining clip and pull the wiring harness connector apart. Turn the retaining ring counterclockwise to remove it from the rear of the bulb assembly.
Pull the bulb straight back out of the headlight assembly. Push the new bulb into the headlight assembly until it locks into place. Replace the retaining ring and turn it clockwise to secure it.
Press the electrical connection together until the retaining clip clicks into place, securing the connector. Push the locking tabs back down around the bulb socket.
Close the bonnet of the car and test the headlights to be sure they function properly.
