Solution

1. Preparation

Gather necessary tools: OBD-II scanner (optional), multimeter, socket set, replacement bulbs, fuse puller.
Ensure the vehicle is parked on a flat surface, turn off the ignition, and disconnect the battery to prevent electrical shock.

2. Inspect and Replace Headlight Bulbs

Sub-steps:
1. Open the hood and locate the headlight assembly.
2. Remove the dust cover (if applicable) by twisting it counterclockwise.
3. Disconnect the electrical connector from the back of the headlight bulb.
4. Remove the old bulb by turning it counterclockwise and pulling it out.
5. Insert the new bulb into the socket and turn it clockwise to secure.
6. Reconnect the electrical connector and replace the dust cover.

3. Check and Replace Headlight Fuses

Sub-steps:
1. Locate the fuse box (usually found under the dashboard or in the engine compartment).
2. Refer to the fuse diagram on the cover to find the headlight fuse.
3. Use a fuse puller to remove the fuse and inspect it for continuity.
4. If blown, replace it with a fuse of the same amperage rating.
5. Reinstall the fuse and close the fuse box.

4. Test Headlight Relay

Sub-steps:
1. Locate the headlight relay in the fuse box as indicated in the owner's manual.
2. Swap it with a similar relay (e.g., horn relay) to test functionality.
3. If headlights work with the swapped relay, replace the faulty relay with a new one.

5. Reconnect Battery

Reconnect the battery terminals, ensuring they are tight and secure.
Close the hood and check the operation of the headlights.
