Solution

1. Preparation

Gather tools including a multimeter, socket set, and screwdrivers.
Ensure vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shock.

2. Inspect Bulbs

Open the hood and locate the headlight assembly.
Remove the headlight assembly cover by unscrewing or unclipping it.
Carefully remove the bulb socket from the assembly.
Inspect the bulb for any broken filaments. Replace if necessary with a compatible bulb (e.g., H11 for low beams, 9005 for high beams).

3. Check Fuses

Locate the vehicle's fuse box, typically found under the dashboard and/or in the engine compartment.
Identify the headlight fuse(s) using the fuse diagram on the cover.
Remove the fuse and inspect it. If the metal strip is broken, replace it with a fuse of the same amperage (usually 15A or 20A).

4. Test Headlight Switch

Reconnect the battery temporarily.
Use the multimeter to test the headlight switch for proper function.
Disconnect the switch and check for continuity across the terminals when the switch is activated. Replace the switch if it fails the test.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the headlights for any signs of wear, fraying, or corrosion.
Clean any corroded connectors with electrical contact cleaner and ensure they are securely connected.

6. Verify Battery Condition

Test the battery voltage with a multimeter. A healthy battery should read around 12.6 volts when fully charged.
If the voltage is low, recharge the battery or replace it if it fails to hold a charge.
