QUOTE: Originally posted by jimrice4449 Scratch the above. As you seem to already know, the green and red were next to one another. The red to the rear would be illuminated when running and the green to the front. When in the clear in a siding the red to the rear would be changed to green. As to which color went to which side I don't know but, lacking hard data, a good guess would be green to the right and red to the left (as in air and sea navigation lights)
