As an aside, are there real L-shaped traffic light stacks? I’ve always seen them with the arrow at the bottom. The direction of the arrow makes it perfectly understandable without putting it off to the side. But I could imagine a traffic light company marketing these.

Depends on the country. I’ve only seen these.
It’s informative in that you can guess what the extra light is even when off.
I guess, but in my experience there’s red, yellow, green, and any extra bottom one is an arrow.
With us, it can be an arrow right, an arrow forward, a light saying bus, a bunch of things
