How to operate the interior light to turn on when opening the door and off when closing it?

There are three switches for the interior reading light: one is the constant-on switch, another is the constant-off switch, and the third is the switch that turns the reading light on when the door is opened and off when the door is closed. Here is an introduction to the lighting functions: 1. Position lights: Also known as marker lights, their function is to indicate the presence and approximate width of the vehicle. 2. Low beam headlights: These are used for night driving in urban areas. 3. Front and rear fog lights: When visibility is low in foggy conditions, the driver's line of sight is limited. Fog lights have strong penetration, increasing the vehicle's operational distance and improving the driver's visibility.
This operation is quite simple. Most car dome light switches have three modes: ON, OFF, and DOOR position. Normally, just set the switch to DOOR position - the light will automatically turn on when you open the door and turn off about 10 seconds after closing, which is quite convenient. I keep my car's setting on this mode all year round, especially useful at night when fetching items without fumbling for the switch. Some vehicles even allow you to adjust the illumination duration through the infotainment screen, while more luxurious models may offer adjustable light brightness. If your car has these features, you can check the manual for specific operations. If your switch only has ON and OFF positions, try pressing and holding the switch for a few seconds - some older models use this method to toggle modes. If it still doesn't work, check the door lock sensor as it might occasionally get stuck and become unresponsive.
