Step 1: Locate the Headlight Assembly

Pop open the hood of your Jetta and locate the headlight assembly that needs to be replaced. The headlight assembly is the housing that contains the headlight bulb.

Step 3: Disconnect the Electrical Connector

Once the headlight assembly is loose, locate the electrical connector at the back of the assembly. Press down on the release tab and gently pull the connector straight out.

Step 4: Remove the Old Bulb

  • For HID bulbs: Push down on the metal clip that holds the bulb in place and pull the bulb straight out.

Step 5: Insert the New Bulb

  • For halogen bulbs: Insert the new bulb into the socket and twist it clockwise to secure it.
  • For HID bulbs: Push the new bulb into place and secure it with the metal clip.

Step 6: Reconnect the Electrical Connector

Plug the electrical connector back into the headlight assembly until you hear a click.

Step 7: Reinstall the Headlight Assembly

  • For halogen bulbs: Align the headlight assembly with the mounting points on the vehicle and push it back into place. Tighten the two bolts to secure the assembly.
  • For HID bulbs: Align the headlight assembly with the mounting points on the vehicle and push it back into place. Tighten the two Torx screws to secure the assembly.
