I had dead battery yesterday.  Chalked it up to not closing door completely.  Recharged battery and took if for a drive to make sure it had nice long charge.  
When I turned off key and closed the door the normal delay for the interior lights took place but I noticed the lower sect ion of the instrument panel lights we still lit. 
I couldn't wait long enough to see them go out and half expected to have another dead battery this morning.  Not the case and the lights were off when I went out to the car.
Is there an extra long delay on these lights?
