Frequently Asked Questions

Q: What should I do if my headlights are not working?

A: Check the headlight fuses and relays first. If those are not the problem, check the wiring and connections for any damage or loose connections. If you still can’t find the problem, you may need to take your truck to a mechanic.

Q: Can I replace my headlights myself?
