Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery cable for safety.

2. Check and Replace Brake Light Bulbs

Tools Required: Socket set, gloves
Steps:
1. Open the trunk and locate the brake light assembly.
2. Remove the screws or clips holding the assembly in place.
3. Gently pull the assembly out and twist the bulb socket counterclockwise to remove the bulb.
4. Inspect the bulb; if the filament is broken or the glass is darkened, replace it with a new bulb of the same type.
5. Reinstall the bulb socket, securing it by twisting it clockwise, and reattach the brake light assembly.

3. Check and Replace Fuse

Tools Required: Fuse puller or pliers
Steps:
1. Locate the fuse box, usually found under the dashboard or in the engine compartment.
2. Remove the cover and find the fuse designated for the brake lights (refer to the owner's manual for specific location).
3. Pull the fuse using a fuse puller and inspect it; if the metal strip is broken, replace it with a new fuse of the same amperage.
4. Reinstall the fuse and replace the fuse box cover.

4. Test and Replace Brake Light Switch

Tools Required: Multimeter, screwdriver
Steps:
1. Locate the brake light switch, usually mounted above the brake pedal.
2. Disconnect the electrical connector from the switch.
3. Use a multimeter to test for continuity; if there is no continuity when the pedal is pressed, replace the switch.
4. To replace, remove the mounting screws, install the new switch, and reconnect the electrical connector.
