Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Headlight Bulbs

Remove the headlight assembly by unscrewing the retaining screws.
Disconnect the wiring harness from the bulb.
Remove the old bulb by twisting it counterclockwise.
Install the new bulb by aligning it with the socket and twisting it clockwise.
Reconnect the wiring harness and re-install the headlight assembly.

3. Check and Replace Headlight Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the fuse for the headlights and check for continuity using a multimeter.
If the fuse is blown, replace it with a new one of the same amperage.

4. Inspect Wiring Harness

Examine the wiring harness connected to the headlights.
Look for any exposed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors as necessary.

5. Test Battery and Connections

Use a multimeter to check the battery voltage; it should read around 12.6 volts when fully charged.
Start the vehicle and measure voltage again; it should read between 13.7 to 14.7 volts.
Ensure all connections to the battery and alternator are tight and free from corrosion.
