Hello. Normally the headlight bulb could just be blown out and this problem can be easily fixed by replacing the bulb, but there are some other less likely possibilities to explain why your headlight doesn’t work. There are control unit fuses and relays in your car’s make and model that are a part of the headlight system as well. A blown fuse or broken relay can cause the headlight to not work. There is also a control unit for the entire headlight system which is controlled by the car’s computer. If that is not working properly, it could also be the cause of your headlight not working. A certified technician, like one from YourMechanic, can run a diagnosis of your headlight system and make recommendations as to necessary repairs.
