The brake lights on my '02 F150 have started flashing spontaneously ie - with no one in truck. This lasts for a few minutes, then stops, but can start again a few minutes later. The fear of course is that someday lights could come on and stay on, resulting in dead battery.

I do have a trailer brake controller that has been on truck ten years. Read something on internet that brake pedal switch might be going bad (??). Any one else observed this strange behavior?

 

I'm not going to tell you that it isn't possessed, don't want your spook to get mad at me and haunt my ex. BUT, Could it be an alarm getting activated without activating the horn?

 

Does your truck have the cruise control recall update? It changes the wiring harness for the cruise control and brake stop lamp switch rewired to prevent fires.

 

The good news - no ghosts or spirits causing brake lights to intermittently come on. I installed new brake light switch, and that seems to have eliminated the problem. New switch was about $15 at NAPA.
