Abstract
Abstract A trailer hitch alignment device which allows the driver of a vehicle to align the hitch of the driven vehicle with that of its trailer with no aid from another individual. The invention utilizes two masts having acrylic flags attached thereto mounted upon the hitch components of the respective vehicles to provide visual reference points for the driver. The acrylic flags are bright in color which allow them to be sufficiently illuminated by the reverse lights of the towing vehicle during times of darkness, thereby making night-time hitch alignment possible. Each mast is mounted to a hitch component via a dome-shaped base having several magnets underneath. The magnets provide the attraction force necessary to mount the masts to the hitch components and the shape of the mounting bases provide the bases with the ability to mounted upon virtually any hitch configuration. The mountings are further secured through the use of velcro-type straps which extend from the mounting bases to the hitch components. This enhances stability and, therefore, performance, of the invention when alignment is required over rough terrain or high winds. The invention further has a swing arm offset bracket to allow for the mounting of the masts on towing vehicles having spare tires mounted on their rear.
