Why don't other cars flash their anti-theft lights?

Generally, the anti-theft light will automatically flash after locking the car. If it doesn't flash, it's mostly because the car hasn't been locked. Here is some information about the anti-theft light: 1. Operation method: Engine electronic anti-theft system; Each key has an anti-theft transponder embedded in it. When the key is inserted into the ignition switch lock cylinder and turned to the "ON" position, the electronic anti-theft ECU communicates with the key via radio frequency; If the key is confirmed to be legal, the anti-theft ECU will verify the password with the engine ECU; If the password verification is correct, the engine will be allowed to start. 2. Precautions: (1) When inserting the key into the ignition switch lock cylinder and turning it to the "ON" position, do not place items with strong magnetic fields near the ignition switch lock cylinder. (2) Do not expose the key to extremely high or low temperatures.
Having driven for over a decade, I've noticed that some older or basic model cars don't have any anti-theft system at all, so naturally there's no flashing light. Most new cars nowadays come with this feature, but it depends on how you lock the car. If you use the key fob to lock it properly, that little red light will flash a few times to remind you the system is activated. If it doesn't flash, it might be because the battery is dead or the door wasn't closed properly when locking. I've seen a neighbor's car where the bulb burned out from prolonged parking. The purpose of this is to deter thieves, so it's important to develop good habits and check it regularly when driving.
