In most modern vehicles, the headlights do not automatically turn on when the car is running. However, some vehicles do have a feature called "automatic headlights" or "daytime running lights" that will turn on the headlights when the car is started. This feature is typically found in newer vehicles, and it can be turned on or off in the vehicle's settings.
For vehicles that do not have automatic headlights, the driver will need to manually turn on the headlights when it is dark or when driving in conditions with poor visibility. This can be done by using the headlight switch, which is typically located on the dashboard.
