security indicator light

So I have noticed over the years that my security light at night blinks (obviously) and it is usually a slow blink. Sometimes it blinks rapidly. I have a blue security light in my 2010 sxt. I am not sure of the exact system as I bought the car used but they said there wasn't any after market...

I noticed the security indicator light (solid red dot at top of instrument lights) was flashing every once in a while a few months back, but now I'm seeing it happen a little bit more wide spread. It does happen while driving and I have not noticed any change in the performance of the vehicle...
