What is the flashing red light after locking the car?

[LoganFitz]

Locking the car after the red light is the anti-theft light, usually located at the lower part of the front windshield, at the intersection with the A-pillar. Generally, when the owner presses the lock button on the smart key, the car's anti-theft system is activated, and then the anti-theft light will flash. The anti-theft light is not only red; some models have blue lights. The power consumption of the engine anti-theft light is very minimal, almost negligible, so there is no need to worry about battery drain. The engine anti-theft technology works by shutting down or deactivating all systems in the car before unlocking. Even if someone forcibly starts the starter motor in the engine, the EFI system will not inject fuel, and the ignition system will not work, making it impossible to steal the vehicle.
