I just received a set of these signals 3 over two (see slink below) i am trying to wire them so that they display Green Over Red but for some reason I am not able to have the green led on top be on at the same time the bottom red led is on. I am able to have it be green over green and yellow over red? I can't figure this one out..???
These signals are made in China and come with no paper work or wiring diagrams. From what i can see is that they tied all of the commons together leaving one wire for each LED so in my case I have five wires one for each LED and they are color coded to match the color of the bulb. I am able to light each bulb individually.
