I had the same problem,  whilst driving along the rear interior light would
come on.  The cause of  my problem was the sliding door.  As I was driving
along it  was unlocking and turning the light on.  You dont say whether your
light is the one above the sliding door if it is dont forget to look in this
direction also.   There is a lot of traffic lately re sliding doors and I know
it was the cause of my problem.
