The above answer I believe is correct for the period from 1938 and later. Prior to the 1938 Rulebook the lens to the front and side would display green and red to the rear, unless on a siding (in the clear) to be passed by another train, then the orientation of the markers was adjusted to show green to the front, side and rear (Rule 19 from the 1924 D&RGW Rule Book)
