Solution

1. Preparation

Gather tools: flathead screwdriver, Phillips screwdriver, and gloves.
Park the vehicle on a level surface and turn off the ignition.
Open the hood and secure it with the prop rod for safety.

2. Remove the Headlight Assembly (if necessary)

Locate the screws or bolts securing the headlight assembly.
Use a Phillips screwdriver to remove the screws.
Gently pull the headlight assembly out from the front of the vehicle, being careful not to damage any clips or wiring.

3. Remove the Old Bulb

Locate the bulb socket at the rear of the headlight assembly.
Twist the bulb socket counterclockwise to release it from the housing.
Carefully pull the old bulb straight out of the socket.

4. Install the New Bulb

Take the new bulb (ensure it's the correct type: typically H7 for the X3 G01) out of its packaging.
Avoid touching the glass part of the bulb with bare hands; use gloves or a cloth to prevent oil contamination.
Insert the new bulb into the socket and push it in until it clicks into place.
Reattach the bulb socket by aligning it with the housing and twisting it clockwise until secure.

5. Reinstall the Headlight Assembly (if removed)

Align the headlight assembly back into the housing.
Secure it by re-inserting and tightening the screws or bolts that were removed.

6. Test the New Bulb

Turn on the vehicle and activate the headlights to verify that the new bulb is functioning properly.
