Will the car lights stay on after the key is removed?

After removing the car key, the lights may remain on for about 30 seconds before automatically turning off. This is because the headlights have a delayed shutdown feature after the vehicle is turned off. Car headlights, commonly known as headlamps, come in two types: low beam and high beam. Their main function is to provide illumination for nighttime driving. Low beams are used for city roads with streetlights, while high beams are for roads without streetlights or highways in rural areas. There is also a function to switch between low and high beams, which is used for signaling or overtaking. How car headlights work: The sensor, composed of electronic components like photoresistors, sends electronic signals to the ECU to control the turning on or off of the headlights and the switching between low and high beams. When driving, if the environment suddenly becomes dark, the headlights will automatically turn on. They will automatically turn off when there is sufficient light. During nighttime encounters with other vehicles, the headlights will also automatically switch between low and high beams. The role of car headlights: Automatic headlights can turn on when the owner forgets to switch them on, eliminating the need to manually toggle the switch when illumination is required. They can also automatically turn off based on the intensity of ambient light.
