What is the reason why the interior light stays on and cannot be turned off?

[VonWillow]

The reasons why the interior light stays on and cannot be turned off are as follows: 1. It may be in the always-on mode: Generally, there is a button next to the light on the top of the cabin with three modes, namely ON (always-on mode), DOOR (light turns on when the door opens and off when it closes), and OFF (off mode). It is usually set to DOOR mode, where the light automatically turns on when the door is opened and off when it is closed. If the button is set to ON, the light will remain on and needs to be manually turned off. 2. The light on the top of the cabin may not turn off if the door is not properly closed, so the door status should be checked: Some car interior lights can be pressed to turn on or off, a feature many car owners are unaware of. You can try pressing the light on your car's ceiling to see if it operates this way.
