If your headlights suddenly go out at night, what should you do first?

In the event your headlights go out at night, the safest first action is to turn on your hazard lights. This provides a clear signal to other drivers that you are experiencing a problem and may not be able to move safely. Hazard lights can alert surrounding vehicles to your situation, helping to prevent potential accidents, as your vehicle could become much less visible without functioning headlights.

While turning on interior lights can help other drivers see you, it doesn’t address the immediate need to indicate that you are having an issue on the road. Utilizing high beams would not be beneficial if the headlights are already out, and pulling over immediately may not be feasible or safe without first alerting other drivers. These actions prioritize safety and communication in such an unexpected situation.
