Abstract
Apparatus and a method for its use to assist an operator of a towing vehicle in backing the towing vehicle accurately into a position in which parts of a hitch can be mated to connect the towing vehicle with a trailer. A camera in a towing vehicle module provides the towing vehicle operator a video image of the trailer and a target mounted on it. A beam of light from the towing vehicle module and falling on the target is visible in the video image to show when the towing vehicle approaches and reaches a position in which the hitch can be mated.
