If you only have one head light that is not working it is typically caused by a bulb that has failed. One your vehicle I have had a lot of bulb connections fail and cause this. I would typically start by turning the lights on and wiggling the connection to see if the bulb lights. If it does replace the bulb. Also see if the bulb filament looks broken. If it is then replace the bulb.
