Audi A3: How to Replace Headlight Bulbs

Material Needed

  • Replacement headlight bulb

Make sure you have the right bulb for your car. Some models use halogen and others use HID xenon bulbs. Also, make sure that your replacement bulb is the right fitting.

Step 1 – Remove the old headlight bulb

Open the hood of your car by pulling on the hood release lever by the driver's side kick panel. If you look at the back of your headlights, you should see a black cover with a tab on the top. Push in the tab and release the cover. Set the cover aside for now. Reach inside the back of the headlight housing for the back of the headlight socket. Twist the socket counterclockwise and pull it out.

Pro Tip

Some newer models have bulbs that are harder to reach. In order to replace them, you'll need to tilt the front wheels and remove the fender liner. When you remove that, you'll be able to reach the headlight housing and replace the bulb.

Step 2 – Install new bulbs

Pull the old bulb from the bulb socket and carefully insert the new bulb. Insert the bulb socket into the headlight housing and twist it clockwise to lock it into place. Replace the cover to the back of the headlight housing and snap it into place. Start the car and test the headlight bulbs.

Pro Tip

Be careful not to touch the glass of the bulb. This will transfer grease to the glass, creating hot spots that will cause the bulb to burn out.
