At this point I would bet money it's a bad ground. With the engine off, the
lights are getting their ground through some circuit that is off with the
engine off (question about if this is truly tied to the engine running or
just the run vs. accessory vs. off position of the key switch hasn't been
answered yet).

But I'll bet it's similar to the situation that happens sometimes where a
persons brake lights only work when the headlights are off or the tail
lights work only when the brake pedal isn't pressed.

Bad ground.
