BACKGROUND OF THE INVENTION
The present invention relates to the field of facilitating the connection of trailers, more specifically, an accessory configured for use in hooking up trailers to vehicles.
Attaching a trailer to a vehicle requires backing the vehicle towards the trailer in a manner that aligns the vehicle and trailer for coupling. This can be difficult for drivers inexperienced with using trailers and is, unfortunately, a common problem across all types of trailer hitches.
The most common solutions strategies to solve this problem involve: 1) a strategy of trial and error wherein a driver gets in and out of the vehicle to see where the vehicle is relative to where the vehicle needs to be; or, 2) a two person strategy wherein a second person, who is able to see the trailer hitch, directs the driver to perform the maneuvers required to get the vehicle into position.
