Solution

1. Preparation

Gather tools: screwdriver set, multimeter, replacement bulbs (if needed), new fuses, and possibly a headlight relay.
Ensure the vehicle is parked in a safe location, engine off, and keys removed from the ignition.

2. Check Headlight Switch

Remove the headlight switch from the dashboard using a screwdriver.
Test the switch with a multimeter to ensure it is functioning correctly.
Replace the switch if it is found to be defective.

3. Replace Headlight Bulbs

Open the hood and locate the headlight assembly.
Remove the headlight cover and disconnect the wiring harness from the bulb.
Twist the bulb socket counterclockwise to remove it from the assembly.
Replace with new bulbs, ensuring they are the correct type (H7 for XC60).
Reconnect the wiring harness and replace the headlight cover.

4. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the headlight fuse using the diagram on the fuse box cover.
Remove the fuse with a fuse puller and inspect it for continuity.
Replace with a new fuse of the same amperage if it is blown.

5. Check Wiring and Relay

Inspect the wiring harness for any visible signs of wear, fraying, or corrosion.
If a relay is present, remove it from the fuse box and test it for continuity.
Replace the relay if it is defective.
