Chrysler Repair: 300M interior/exterior lights flash randomly, negative battery cable, fog lamps

Question
I have been experiencing a problem with my 2000 300M.  The interior/Dashboard lights flash on and off randomly.  At first it happened only when I was driving and seemed to be during dusk conditions so I thought it might be light sensor related. The lights would flash on and off  (1 sec on the 1 sec off) until I turned the headlights to manual then back to automatic.  However, last night the car was in the driveway, not running and it started the same thing.  The interior lights AND the head lights started flashing on/off.  It was dark and I didn't see it myself but it might be that it started when the driveway light came on when my son walked in front of the garage light sensor.  It's weird that the car was locked, had been shut down for 6 hours and then all the electrical activity started.
