Is it normal for the security light to keep flashing?
2 Answers
It is not normal. The security light is a safety warning light. Here are the specific details: Introduction: If the security light is on, it indicates that the vehicle's anti-theft system is in a locked state. After turning off the engine, if you lock the doors and the light flashes, it is normal, as it means the engine's electronic anti-theft lock is active. If it doesn't flash, the anti-theft system may not be engaged, possibly because the doors are not properly closed. Additional Information: The security light flashing could also be a reminder to fasten your seatbelt. Fastening the seatbelt will put the light in a short-circuited state. You can also try restarting the car engine or turning off the main switch to see if these methods can turn off the security light.
Seeing your question reminds me of a similar situation I encountered a few years ago. The flashing security light on a car indicates that the anti-theft system is functioning normally. For example, after locking the car, it will flash intermittently, signaling that the system is activated to protect the vehicle. This flashing is usually an energy-saving design of the LED light, blinking every few seconds to save power while also serving as a warning to others. However, if it keeps flashing non-stop or the flashing pattern suddenly changes—such as speeding up or staying lit continuously—there might be an issue. Common causes include low battery voltage, system malfunction, or wiring problems. Last time my car's battery was aging, the light flashed abnormally, and it only returned to normal after replacing the battery. I recommend first checking the user manual for the standard flashing pattern. If the manual states it's normal but you're still concerned, visit a professional shop for an inspection. After all, a malfunctioning security device could lead to anti-theft failure or battery drain, so addressing it early is best. Confirming the light flashes after parking can also help you verify if the car is properly locked—a handy feature in daily use.
