Will the anti-theft light flashing continuously for ten days drain the battery?

The anti-theft light flashing continuously for ten days will not drain the battery. The power consumption of the anti-theft light is minimal and well within the supply capacity of the vehicle's battery. Under normal circumstances, the anti-theft light will continue to flash unless the car's battery is disconnected. The function of the anti-theft light: For the car's anti-theft light, it primarily serves as a warning reminder. The owner can tell that the car is in anti-theft mode after locking it by the flashing of the anti-theft light. The owner does not need to worry about the flashing of the light. Precautions for using the anti-theft light: Generally speaking, when the car door is opened and the engine is started, the flashing of the anti-theft indicator light indicates that the vehicle's anti-theft system is activated and in working condition. If the battery is dead, the vehicle's anti-theft system will lock the vehicle, making it impossible to deactivate the anti-theft system via the remote control, open the door, or start the engine. It is necessary to use the mechanical lock to open the door and either jump-start or replace the battery.
To be honest, as someone who frequently works on cars, I don't think the anti-theft light flashing continuously for ten days would drain the battery significantly. Most anti-theft lights use LED bulbs, which consume very little power—only about a few tenths of a watt. Assuming it flashes 24 hours a day, the power consumption would be less than 0.1 kWh. Compared to a standard car battery with 60Ah capacity, it could last several months without issue. I've seen many cars parked in garages for weeks with the light still flashing, and the battery works just fine. The key factor is the battery's health—if it's old or has leakage issues, then there might be a slight risk. I recommend taking short drives regularly to recharge the battery or adding a voltage monitor as a precaution. Don't worry too much—modern car anti-theft systems are designed with power optimization in mind.
