Why is there always a red light flashing inside the car?

[GenevieveFitz]

When there is always a red light flashing inside the car, it indicates that the vehicle's anti-theft function is activated. This indicator light flashes after the car is locked, which is a normal phenomenon. If the light does not flash, it means the car is not properly locked or there is a malfunction in the anti-theft system. Here is a detailed introduction about the car anti-theft system: 1. Definition: The car anti-theft system refers to a system designed to prevent the theft of the car itself or items inside the car. 2. Composition: Car anti-theft has evolved from purely mechanical key anti-theft technology to electronic anti-theft and biometric electronic anti-theft. The electronic anti-theft system mainly consists of an electronically controlled remote or key, electronic control circuit, alarm device, and actuator. 3. Classification: There are five major types of anti-theft systems: key-controlled anti-theft system, remote-controlled anti-theft system, alarm-type anti-theft system, anti-theft system with both anti-theft alarm and vehicle movement prevention, and electronic tracking anti-theft system.
