I just recently noticed a rapidly flashing green LED under the dash, left of the steering wheel. It goes out if a door is opened. It may have always done this but I just noticed it and haven't been able to find what it means by trying to Google it. Does anyone know if this is something I should be concerned about?
Thanks in advance.

I've never seen such a light on my 2008 Sonata.

 

I had never noticed it before either. Now I notice it every time I get in the car. Car is 100% stock.

 

I agree with Ken. It doesn't seem original. Post a picture.
