My parking lights go on and off when the car is off.
I had problems with the headlights flashing about 3 years ago and fixed it with spaying contact cleaner and air in the multi function switch and that fixed that. I tried the same thing several times to try and fix the blinking tail lights but doesn't work. I just replaced the (LCM) lamp control module but still does it. Somebody told me today that it could be the security module. Anybody have any thoughts. I'm thinking that the multi-function switch needs to be replaced. Is there a fuse or a way to shut down the (LCM) and just turn the lights on and off manually?
Any help will be much appreciated.

Under the back seat fuse boxes, the one closest to the hump, second Maxi fuse down should be a blue 60 amp fuse, cover has it labeled exterior lighting. Its a pain to have to get to but it saves the battery.
Did you try doing the spray contact cleaner in the Hazard light section of the switch. That is where mine was messing up at.
