Solution

1. Preparation

Gather tools: flathead screwdriver, gloves, clean cloth.
Ensure the vehicle is turned off and parked on a flat surface.
Open the hood and secure it with the prop rod.

2. Access the Headlight Assembly

Locate the headlight assembly at the front of the vehicle.
Remove any covers or protective caps that may obstruct access to the headlight bulb.
If necessary, use a flathead screwdriver to carefully pry off plastic clips or covers.

Locate the bulb socket at the rear of the headlight assembly.
Twist the bulb socket counterclockwise to detach it from the assembly.
Carefully pull the old bulb out of the socket, avoiding touching the glass with bare hands.

4. Install the New Bulb

Take the new headlight bulb (ensure it matches the specification, typically H11 for Corolla E210).
Insert the new bulb into the socket without touching the glass.
Secure the bulb by twisting the socket clockwise until it locks in place.

Replace any covers or caps removed in Step 2.
Close the hood securely.
