Solution

1. Preparation

Tools Required:
- Screwdriver set
- Multimeter
- Replacement bulbs (if needed)
- Fuse puller
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Bulbs

Remove the tail light assembly by unscrewing the retaining screws (refer to the owner's manual for specific locations).
Carefully pull out the bulb socket from the assembly.
Remove the old bulb and replace it with a new one, ensuring it is properly seated.
Reinsert the bulb socket into the tail light assembly and secure it back in position.

3. Check and Replace Fuses

Locate the fuse box (often under the dashboard or in the engine compartment).
Identify the specific fuse for the tail lights using the fuse diagram in the owner's manual.
Use a fuse puller to remove the fuse and inspect it for any signs of damage (a broken filament).
Replace with a new fuse of the same amperage rating if necessary.

4. Test Wiring and Connections

Reconnect the battery and use a multimeter to check for voltage at the tail light socket while the headlights are on.
If no voltage is detected, trace the wiring back to the source, checking for any breaks or corrosion.
Repair or replace damaged wiring and connectors as needed.

5. Reassemble

Once all repairs are completed, reattach the tail light assembly and secure it with screws.
Make sure everything is properly aligned and fitted to prevent moisture entry.
