Why does the indicator light stay on when the car door is closed?

The reasons why the indicator light stays on when the car door is closed are: 1. Although the car is turned off, the power is still on, and the dashboard will also remain lit. In this case, simply turn off the power switch and the light switch. 2. The car is turned off, and the power is also off, but the dashboard has a standby function. After the passengers exit and close the car door, the dashboard will automatically turn off. Automobile dashboard indicator lights are divided into three categories: indicators, warnings, and faults. Indicator lights are commonly seen during normal driving, such as light signal lamps, turn signal lamps, and parking lamps, which serve to indicate the status of various vehicle functions. Warning lights have an alert function, such as fuel indicator lights, door status indicator lights, and seat belt indicator lights. Fault lights are important indicators, such as generator fault indicator lights, ABS fault indicator lights, and transmission fault indicator lights.
