Snag Daddy Old Dad, That's a Snag Dandy Snag

The light sometimes in flight will turn on by itself and upon landing the flight crew would report a mechanical issue unrelated to that light. She said mechanics would work on the plane at night and that light would mysteriously turn on when they were working on a mechanical issue on that aircraft. On some warnings when mechanics and flight crew would wake up the plane, I mean, it's turning on the aircraft power, the light would mysteriously be on upon the aircraft being entirely powered up. The crew would encounter a fault or an issue with that aircraft without a prior history. Spooky, right? So it's almost sounds like it's warning people.
