I was able to come up with a second solution (that ended up being wrong), so I believe this puzzle as it stands isn't unique. Still a good puzzle, though.
Jake: Did you miss the "same bulb digit" rule for twins?

This one really would benefit from having an example for the rules, it was extremely obscurely formulated.

I get nervous around concepts like this one; I’m very poor at visualization.
This puzzle is a wonder. Terrific, wish I could give it a higher score than the site allows.
Thank you very much, please keep creating 1 star marvels like this.

Sublime. Really great to see you setting again, especially given the calibre on display here.
