How to Reset Daytime Running Lights: 1 Minute to a Brighter Driving Experience

Daytime Running Lights (DRLs) are essential for vehicle safety, automatically illuminating when your car is in motion to improve visibility. If your DRLs aren't working or a dashboard warning appears, resetting them can often resolve the issue. The reset process varies by make and model, but the general steps include checking your vehicle’s manual, inspecting the DRL fuse, ensuring the bulbs are in good condition, and disconnecting your car battery for a brief period to reset the system electronics. In some cases, the onboard diagnostic (OBD) system may require scanning and clearing error codes. If the issue persists, consulting a professional mechanic might be necessary.
