My apologies.... while the lights are not suspended by wires they are indeed suspended and placed in the middle of the intersections or just entering the intersections by a large extended pole.
Such as in this pic where this question evolved. Who has the right of way here, me in my truck (with the dashcam) about to turn left, or the oncoming white truck which is about to turn right?
NOTE: Both light directions were solid green, no arrows.
