ABSTRACT:
The present invention includes a first laser light source mounted to a towing vehicle and oriented to direct a first laser light beam towards a trailer to impinge on a first marker spot located on a hitch coupler mounted to the trailer. A second laser light source is also mounted to the towing vehicle in spaced apart relation with the first laser light source and oriented to direct a second laser light beam towards the trailer at an angle to the first light beam to impinge on a second marker spot on the trailer when the hitch and hitch coupler are aligned. When the towing vehicle is moved towards the trailer with the first laser beam impinging on the first marker spot and further moved towards the trailer until the second laser beam impinges on the second marker spot, the hitch coupler is aligned with the hitch.
