In a car, 'door' refers to the reading light's activation mode. The term 'door' means that the reading light turns on when the car door is opened. It also illuminates if the door is left ajar or not properly closed, serving as a warning function. The interior reading light typically has three position switches: off, on, and door. When the reading light control switch is set to the 'door' position, the light will turn on upon opening the door. After the driver exits the vehicle and removes the key, the reading light will remain on for 15 seconds before automatically turning off. Additionally, if the mechanical key is not inserted into the ignition switch, turning the ignition switch to the LOCK position will also activate the light.
