Solution

1. Preparation

Gather tools and necessary parts.
Disconnect the vehicle's battery to prevent electrical shock.
Tools Required: Socket set, multimeter, flathead screwdriver, new bulbs, replacement fuses.

2. Remove the Tail Light Assembly

Open the rear hatch and locate the access panel for the tail light assembly.
Use a flathead screwdriver to gently pry off the access panel.
Unscrew the retaining screws securing the tail light assembly.
Carefully pull the tail light assembly away from the vehicle.

3. Inspect and Replace Bulb

Remove the bulb socket from the tail light assembly by twisting it counterclockwise.
Pull out the old bulb and inspect for any signs of damage or blackening.
Insert a new bulb (make sure to use the correct type specified in the owner’s manual).
Reinstall the bulb socket into the tail light assembly by twisting clockwise.

4. Check and Replace Fuse (if needed)

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Refer to the fuse diagram and identify the fuse for the tail lights.
Pull the fuse using a fuse puller or pliers. If the metal inside is broken or the fuse looks burnt, replace it with a new fuse of the same amperage.
