Call me skeptical, but there's no anecdotal evidence for the rings being for gloves. If it were the case, then cars of that era would have been equipped that way everywhere. Gloves were common, yes, as common as hats and coats (which we know there are hooks for, in the picture and many other places still today.)
Anecdotal evidence says "gloves were an item, yes, but were carefully folded and placed in coat pockets, which were hung on hooks.
Now, as to the loops themselves:
They all face the same way at same height/position which suggests something traversing them, either a chord, or a rod/dowel.
I can't see these being for oil lamps. The geometry just doesn't work out for me. I COULD be wrong, but I just don't see it as likely.
The loops are also fairly big, rather too big for a rod/dowel for hanging anything. Again, I COULD be wrong about that, that's just my impression.
As we know anecdotally that pull-chords were common enough and in similar situ to the loops in evidence, that's where I put my money.
Being a good skeptic, I welcome any correction and or further evidence, anecdotal or otherwise.
