Woodland Scenics HO Scale Just Plug Traffic Lights are ready to place right out of the package and come hand-painted and authentically weathered. The Traffic Lights are pre-wired and made for use with the Just Plug Lighting System. Whether at rural intersections or on busy city streets, they add interest to any scene. Pedestal Traffic Lights are single-faced and the package includes two red lights and two green lights, enough for one four-way intersection.
