What are common causes of faulty headlights in a Vauxhall Corsa?

I recently noticed that my headlights are not working properly on my Vauxhall Corsa. I checked the bulbs and they seem to be fine. What could be the cause of this issue?

It's possible that the headlight switch is faulty and needs to be replaced. You can try testing it with a multimeter or have a mechanic check it for you.

Another common cause for faulty headlights is a blown fuse. Check the fuse box and replace any blown fuses.

If the above solutions don't fix the issue, it could be a wiring problem. Have a professional mechanic check the wiring for any damage or loose connections.
