Will the blinking security light Drain my battery on my car?

The blinking security light in your car is designed to indicate that the security system is active and should not significantly drain your battery. However, if your car is not driven for an extended period, even small drains from systems like the security light can contribute to battery depletion. It's a good idea to start the car periodically or use a battery maintainer if you won't be driving it for a while.
