I don't quite see how to make it work, though. Adding the item to the player's inventory has it be a "Misc" class item, which does nothing when you try to activate it.
I have no examples within Fallout 3 of a carryable light so, I don't quite know where to go.
Can anyone direct me in what might be correct for this?
Emulating the pip-boy light has so far not helped me, it looks like parts of that are hardcoded so it is a different beast.
