Studies for japanese traffic lights and a design concept

Mmm... I love worrying about little details like this. Blue ring for "go" is a nice touch. It's relatively easy to come up with a neat, clear, system that in the real world nobody will ever use because, Tradition, by any other name. Alas.

Agreed; I wonder, however, if for the purposes of minimizing issues with colorblindness, it might make sense for the yellow/middle/clear-intersection light to be the hollow icon with "go" and "stop" both remaining solid. Angling the housing to prevent snow buildup is a solid principle, but internal heating elements will likely remain necessary in winters just in case of high winds. Even with heating elements that activate near freezing temperatures, LEDs would still remain more efficient than incandescent bulbs.

I've tested with colourblind simulators and did research online, the red/green stop and go lights are the main problems. especially if you can't recall which order they are supposed to be in
