Troubleshooting and fixing car headlight wiring can seem daunting, but with the right knowledge and tools, it’s a manageable task. This guide will walk you through diagnosing and repairing common headlight wiring issues, helping you get your lights back on the road safely.
Understanding Your Car’s Headlight System
Before diving into repairs, it’s crucial to understand the basic components of your car’s headlight system. This includes the battery, fuses, relays, switches, and the headlights themselves.
