Disconnect the battery to avoid electrical shock.

2. Check and Replace Fuses

Locate the fuse box (refer to the owner’s manual for location).
Remove the headlight fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.
Reconnect the battery.

3. Inspect and Replace Headlight Bulbs

Open the hood and locate the headlight assembly.
Remove the headlight cover or access panel.
Disconnect the wiring harness from the bulb.
Remove the bulb by turning it counterclockwise and pulling it out.
Insert a new bulb (ensure it is the correct type) and secure it by turning it clockwise.
Reconnect the wiring harness and replace the headlight cover.

4. Check Headlight Switch and Relay

If the headlights still do not work, inspect the headlight switch for proper function.
If necessary, replace the headlight switch by removing the steering column cover and disconnecting the switch.
Test the relay by swapping it with another relay of the same type (if applicable) to see if the headlights operate.
