ABSTRACT:
A visual aid device for positioning of a towing vehicle for hitching to a trailer. A vehicle-attachable sighting rod assembly co-operates with a trailer sighting target assembly to guide the vehicle rearwardly into hitching position. Sighting and target rods are so placed as to come together when the vehicle reaches the hitching position. The sighting rod may be attached to be visible along the side of the vehicle, so that an unobstructed rear window is not needed. The target rod is then placed upon the ground to the side of the trailer coupling the same distance that the vehicle sighting rod is from the vehicle coupling. The target assembly may also have another sighting rod, which with the target rod is useful for vehicle direction control, if needed. The assemblies may also be used with the rear window, if it is not visually obstructed. In this case, the target assembly then being attached to the trailer tongue with the target rod rising vertically directly from the coupling to be seen through the window.
