Safety First: Important Precautions

• Park your car on a level surface: This will prevent the vehicle from rolling while you’re working.
• Engage the parking brake: Ensure the vehicle is secure and won’t move.
• Disconnect the battery: This is essential to prevent electrical shock while working on the electrical system. Locate the negative battery terminal (usually black) and loosen the clamp to disconnect it.

Accessing the Headlight Assembly

2. Remove the screws: There will be several screws holding the headlight assembly in place. Use your Phillips and Torx screwdrivers to remove them.
3. Carefully remove the assembly: Once all the screws are removed, gently pull the headlight assembly out of its housing. Be careful not to damage any wires or connections.

Installing the New Headlight Assembly

1. Connect the electrical connector: Align the new headlight assembly with the housing and connect the electrical connector. Make sure the tab on the connector clicks into place to ensure a secure connection.
