    Abstract: A trailer hitch alignment system for allowing a user to easily align a hitch of a vehicle with a trailer hitch. The inventive device includes a control that is mountable to a visor of the vehicle in view of the driver, a receiver unit attachable to the bumper of the vehicle and in communication with the control unit, a transmitter unit removably attachable to a trailer hitch that transmits a locating signal that is detectable by the receiver unit, and a storage case. Electronic circuitry within the control unit determines the position of the transmitter unit from the receiver unit from the reception of the locating signal. The control unit includes a turn right indicator and a turn left indicator for visually indicating to the user whether to turn left or right while backing toward the conventional trailer. The control unit also includes a buzzer and stop indicator light for indicating to the user when the ball hitch is positioned below the coupler of the trailer hitch.
