## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an LED accessory system and more particularly pertains to illuminating a hitch ball area of a towing vehicle to facilitate coupling a trailer to the vehicle in a safe, convenient and economical manner.
2. Description of the Prior Art
The use of towing accessory systems of known designs and configurations is known in the prior art. More specifically, towing accessory systems of known designs and configurations previously devised and utilized for the purpose of illuminating the hitch ball area of a vehicle are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 5,434,552 issued Jul. 18, 1995 to Ems relates to a Trailer Hitch Security System with Separate and Selectively Set Loose Connection and Theft Prevention Alarms. U.S. Pat. No. 6,178,650 issued Jan. 30, 2001 to Thibodeaux relates to a Trailer Hitch Protection System. U.S. Pat. No. 7,032,920 issued Apr. 25, 2006 to Peng relates to an Embellished Vehicle Trailer Hitch Ball Assembly. Lastly, U.S. Pat. No. 7,291,017 issued Nov. 6, 2007 to Fain relates to a Power Interface Device for Trailer Hitches.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe an LED accessory system that allows illuminating a hitch ball area of a towing vehicle to facilitate coupling a trailer to the vehicle in a safe, convenient and economical manner.
In this respect, the LED accessory system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of illuminating a hitch ball area of a towing vehicle to facilitate coupling a trailer to the vehicle in a safe, convenient and economical manner.
Therefore, it can be appreciated that there exists a continuing need for a new and improved LED accessory system which can be used for illuminating a hitch ball area of a towing vehicle to facilitate coupling a trailer to the vehicle in a safe, convenient and economical manner. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of towing accessory systems of known designs and configurations now present in the prior art, the present invention provides an improved LED accessory system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved LED accessory system and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a horizontally disposed tubular reception member having a square cross sectional configuration with an exterior surface and a rearwardly extending interior surface.
Next provided is a hitch ball member having a rearward end with an upstanding ball for receiving a trailer to be towed. The hitch ball member has a forward end with a forwardly extending projection positionable in the interior surface of the reception member.
A base member is next provided. The base member has a top and a bottom with laterally spaced sides. The base member has a generally planar front face and a generally planar rear face. A square opening is provided through the base member. The opening is slidably received by the exterior surface of the tubular reception member with the rear face facing rearwardly toward the upstanding ball.
Next provided are two angularly disposed threaded apertures extending from the top of the base member to the opening. A locking bolt is threadedly received within each threaded aperture to selectively secure and release the base member with respect to the tubular reception member.
A cylindrical hole extends through each side of the base member. A battery extends through each hole. A lens cap is threadedly coupled to the rear face of the base member rearwardly of each hole to create a light chamber rearward of each side of the base member. A battery switch is threadedly coupled to the front face of the base member forwardly of each hole to energize and de-energize the battery upon depressing the switch.
Next a printed circuit board is provided. The printed circuit board has rearward facing LEDs. Light emitting diodes are commonly referred to as LEDs. The LEDs are in a square grid within the chamber. The LEDs are adapted to be turned on and off through the energizing and de-energizing of the battery upon the pressing of the switch. The LEDs are at an elevation essentially equal to the ball for maximizing illumination.
Additionally, in the preferred embodiment, a laterally positioned link is provided. The laterally positioned link extends laterally from and is pivotably secured to each side of the base member for supplemental attachment of the trailer.
Lastly provided is a television camera within one of the chambers operatively coupled to the battery.
