Okay, this is a little different and could probably apply to any rifle-mounted light, but...
My 870 has a SureFire fore-end without the "disable" switch.
I have it sitting in the front of my safe for speedy access. On the door to my safe I have attached cheap holsters for handguns. Turns out that when the door closed, one of the handguns activated the SureFire on the shotgun. I had recently put a P61 bulb in it, and when I opened the safe about 15 minutes later, the SureFire was too hot to touch.
I don't know if it could have started a fire before the batteries ran out (doubtful) but it certainly could have depleted the batteries and burned out the bulb which I'm sure I would discover when I needed it most.
Anyway, for those who wonder "Does the light in the fridge stay on when I close the door," the answer is "Maybe!"
