The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A trailer hitch alignment system comprising:
at least two separated light sources mountable on a tow vehicle and capable of projecting intersecting beams of light to a set focal point which focal point is adjustable such that the focal point may be set to the distance between the vehicle and a trailer to be coupled to the vehicle so the focal point of said light beams is on said trailer when said trailer is coupled to said tow vehicle.
2. The trailer hitch alignment system of claim 1 including three separate light sources, one of which is mountable to project its light beam directly in line with a hitch of said tow vehicle.
3. The trailer hitch alignment system of claim 2 wherein said light sources which are not mountable to said vehicle to provide intersecting light beams are constructed and arranged such that the light sources may be adjusted so their projected beams intersect at a focal point at a different length from said vehicle.
4. The trailer hitch alignment system of claim 3 further including a target device capable of being secured to a trailer upon which light from said light sources may be projected.
5. The trailer hitch alignment system of claim 4 wherein said target device is constructed and arranged to provide light shielding to make said light beams more visible on said target device in high ambient light conditions.
6. A trailer hitch alignment system comprising:
a) a light source mountable on a tow vehicle which projects light out in at least three separate points, at least two of said separate points being formed by light beams from said light source that are not parallel to the other said separate points; and
b) a target device mountable to a trailer including indicia which may be positioned such that the indicia are aligned with projected light from said light source when said tow vehicle is coupled to said trailer.
7. The trailer hitch alignment system of claim 6 wherein said light source projects light outwardly to define a two dimensional shape.
8. The trailer hitch alignment system of claim 7 wherein said light source projects light outwardly in the shape of a rectangle, with the rectangle being larger the further the light is from the light source.
9. A trailer hitch alignment system comprising:
a) a vehicle having a front end and a back end, said back end including a trailer hitch mechanism for coupling to a trailer; and
b) at least two separated light sources mounted to said vehicle and capable of projecting intersecting beams of light to a set focal point which focal point is adjustable such that the focal point may be set to the distance between the vehicle and a trailer to be coupled to the vehicle so the focal point of said light beams is on said trailer when said trailer is coupled to said tow vehicle.
10. A vehicle backup system comprising:
at least two separated light sources mountable to a trailer and capable of projecting intersecting beams of light to a set focal point which is a point beyond a back end of said trailer such that said separated light sources may be directed onto a target and the distance to said target from the back of said trailer may be determined by observing the separation of the light beams on the target while backing up the trailer.
11. The vehicle backup system of claim 10 further including a loading dock target device mountable to or adjacent to a loading dock such that said light beams from said trailer may be directed upon said target device.
