Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a flat surface.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the fuse for the exterior lights using the diagram on the fuse box cover.
Check the fuse for continuity using a multimeter; replace it if blown (typically a 10A or 15A fuse).

3. Check Light Bulbs

Access the light bulb assemblies by removing any covers or screws as needed.
Remove the bulbs and visually inspect them for breakage; replace any faulty bulbs with the correct type (e.g., H11 for headlights).
Reassemble the bulb housing securely.

4. Test Wiring and Switches

Inspect wiring harnesses for damage, corrosion, or loose connections, especially at the light assemblies and fuse box.
Use a multimeter to test the headlight switch and multifunction switch for continuity.
Replace any defective switches as necessary.

5. Reconnect Battery and Test Lights

Reconnect the negative terminal of the battery.
Turn on the vehicle and check all exterior lights for functionality.
