Abstract
Abstract A visual aid to assist a driver in maneuvering a towing vehicle toward a trailer or other vehicle to be towed for precisely aligning the hitch components of the two vehicles. The device mounts only to the towed vehicle and includes an integral bumper member to protect the vehicles should the driver back too far. The device is adaptable to all conventional trailer hitch components and is simple and easy to use. It comprises a universal adaptor, a sighting mast and a strap for attaching the assembly to the towed vehicle. The mast can be mounted in the vertical position for viewing through the back window or at an angle to extend laterally past the side of the tow vehicle to allow the driver to view the mast even if rearward visibility is blocked through the rear window of a tow vehicle. The mast is disturbed from its rest position when the hitch components are aligned. The device is also designed such that it can be mounted to a vehicle to provide an early warning signal to the driver that he is closely approaching an object.
