Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- Socket set
- Screwdriver set
- Multimeter
- Replacement brake light bulbs (if needed)
- Fuse puller or pliers

2. Inspect and Replace Bulbs

Remove the rear light assembly by unscrewing any retaining screws.
Gently pull the assembly out to access the brake light bulbs.
Twist and remove the faulty bulb from the socket.
Insert a new bulb of the same specification (typically 21W for brake lights).
Reassemble the rear light assembly and secure with screws.

3. Check and Replace Fuse

Locate the fuse box, typically found in the engine compartment or under the dashboard.
Use the fuse diagram to identify the brake light fuse.
Pull the fuse using the fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

4. Test Brake Light Switch

Locate the brake light switch mounted on the brake pedal assembly.
Disconnect the switch connector and use a multimeter to check for continuity when the pedal is pressed.
If there is no continuity, replace the brake light switch.

5. Inspect Wiring

Visually inspect the wiring harness leading to the brake light assembly.
Look for any frayed wires, corrosion, or loose connections.
Repair any damaged wiring or connectors as necessary.
