Why does the car's headlights turn on when I remove the key?

The car's headlights may turn on when you remove the key due to a feature designed to enhance safety and convenience. This feature, often called "headlight delay," allows the lights to remain on for a short period to illuminate your surroundings as you exit the vehicle. Additionally, some vehicles have a setting that keeps the lights on until the driver closes the door or a specific time elapses. If the headlights stay on longer than expected, it could indicate a malfunction or a need for adjustment in the vehicle's electrical system.
