[CoreyMarie]

The plus and minus sign light on the car indicates that the vehicle is charging or there is a malfunction in the dashboard system, requiring prompt repair. Car dashboard indicator lights are divided into the following three categories: 1. Indicator lights: The most common lights encountered during normal driving, such as light signal indicators, turn signal indicators, parking lights, etc. Their function is to indicate the status of various vehicle functions. 2. Warning lights: Warning lights serve an alerting function, such as fuel indicators, door status indicators, seat belt indicators, etc. Generally, warning lights turn off after the driver performs the corresponding action, such as the seat belt indicator, which turns off when the seat belt is fastened. 3. Fault indicator lights: Fault indicator lights are also the most important indicators, such as generator fault indicators, ABS fault indicators, transmission fault indicators, etc.
