The car is off. The light switch is off. The parking lights (all four) reman lit. I pulled the fuse ( 9) that should kill them but they stay on. Just before I parked it the auto headlight control was turning on and off. When I parked it the" lights are on "alarmed dinged, but the manual switch was in the off position. To get it to turn off I had to turn the dash dash light/dome light roller switch to the lowest setting.

The lighting system has self-diagnostic functions and a scan tool is required to check for trouble codes which would help to identify and locate the source of the problem.

You should get a scan performed first. These are B codes and normal code readers would not be able to get them.
