A small collection of vintage traffic signals 

Thanks - These are all true favorites of mine. Even the Marbelite (left-most on the floor) is a scarcely found older one with Horni reflectors.

Oooo that's cool!

Not a bad idea - I have actually wired up six signals to a single controller before, but I right now, I really like the portability of each signal with its own circuit board controller.

That makes sense!
