There was lighting up in the dome.
What today would be called “task” lighting, for each row in a downward facing position. Probably (hopefully) very dim.
What I don’t know is if there was floor or stair lighting. My guess would be yes, but I don’t know for sure.
The lighting does not bother me, the shape of the domes, that would bother me more.
I should also add, the color is pretty close and the detail is very nice. Once populated with people, the domes will make a nice focal point.
Otherwise a nice set. I too would like to see these in 18 inch cars… and lowered.
