I still have to work on the start and end time, especially for interior as that got recently added. But that's already the base functionality.
First I load a savegame with activated pipboy light. It gets automatically de- / activated to re-initialize the mod. Going outside automatically activates the light either (as the start and end time is the same. Which means the auto-activation works 24/7).
