When I lived in the US in the late 80s/early 90s, our new construction house had no built in lighting at all save the kitchen, hallways and bathrooms. The bedrooms, living room, dining room, even the little breakfast room/sun room attached to the kitchen, had no ceiling lights.
I think it was just the fashion at the time.
The master bedroom's attached bath had a glass fireplace in the wall between the two rooms, just above the very large tub. You can see right through it provided no logs were in it. I wondered if my dad ever watched my mum poop through it.
