Would offering a lighting alternative help? Perhaps a small corner or table lamp that she could use?
We've been down that road before. She has a small flashlight... .multiple small lamps.
Her habit is that she dresses in the walk in closet. Closes the door and turns light on in there. Of course... .that assumes she wants to be kind and respect me or others that may still be sleeping.
99.9% sure she decided she is going to be pissed off about having to go to work... .and that if she was going to get up... everyone else would too.
BPDish punishment... .pure and simple.
This was one of the topics discussed during P today. Best response is to ignore the past... help "solve" what time she claims to need to be up in the morning... .and see if that can be worked around.
