Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turned off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Access the Headlight Assembly

Open the hood of the vehicle.
Locate the headlight assembly at the front of the vehicle.
Depending on the specific model, remove any covers or panels obstructing access to the headlight bulb.

3. Remove the Old Headlight Bulb

Twist the bulb socket counterclockwise to release it from the headlight assembly.
Carefully pull the old bulb out of the socket. Avoid touching the glass part of the bulb as oils from your fingers can cause premature failure.

4. Install the New Headlight Bulb

Take the new bulb (typically H11 for low beams) and insert it into the socket, ensuring it is securely in place.
Twist the bulb socket clockwise to lock it back into the headlight assembly.

5. Reassemble and Test

If applicable, reattach any covers or panels you removed.
Reconnect the negative terminal of the battery.
Turn on the headlights to verify that the new bulb is functioning properly.
