Above is a picture of my Marbelite 3 Way cluster. Long story short, I noticed signals like these while in NYC and liked them. Some were Econolites, and others were Marbelites. The three signals pictured here are all Marbelite. The signal on the left hand side (cross street) happens to be my very first signal ever in my collection! The signal in the middle was formally an all LED set up, but I have restored it back to incandescent bulbs. This is a two phase set up without peds controlled by my Marbelite Electromechanical Controller. A favorite set up of mine.
