rear cargo light/high mount brake light coming on for no reason

[raggdoll]

Any idea why this light would randomly come on, after I shut off my truck. I'll walk away, the light times out as normal, then about an hour later I go outside and its on?

No, the inside cargo light is not on. It's so weird, I can't figure it out?

Do the high-mount cargo lamps and the brake lamps illuminate (or just one of them)?
