[0004] 2. Description of the Background Art

[0005] The background art illustrates a variety of trailer hitch lighting systems and decorative devices. The light bar safety and signal assembly and method of the present invention builds and improves upon on the attempts of the background art by utilizing fabricated full functioning lights instead of relying just on the brake and signal lights. The safety bar equips the vehicle with an integrated light system that utilizes a wiring harness assembly that may contain driving, brake/signal, flasher/emergency, back-up, strobe, marker, fog and illuminating lights. The present inventor has also determined that there are numerous shortcomings with the previous attempts of the background art that are overcome by the present invention.

[0006] U.S. Pat. No. Des. 338,861 by Lataster shows a light shell bumper attached to a decorative cover for a vehicle trailer hitch tube. U.S. Pat. No. 3,819,206 to Aarons describes a cushion hitch made of toroids (hard elastomeric solid cast urethane) that function as both a spring and a shock absorber (but not vibration control) and other parts made of metal. Because of a close fit of the tube and pin, these components are coated with a material that has a low coefficient of friction such as polytetrafluorethylene. These components also fail to provide ease of attachment.

[0007] U.S. Pat. No. Des. 437,431S Crouse et al. is a design patent for a light weight trailer hitch cover that consists of a basic shell that is illuminated.

[0008] U.S. Pat. No. 5,603,178 to Morrison provides protection of weather and a decorative cover for the trailer hitch and a description of a way to secure the unit to the hitch on the vehicle.

[0009] U.S. Pat. No. 5,979,094 to Bradford, Jr. describes a lighted sign and protected trailer hitch accessory that uses signal lights, brake lights and harness assembly that hooks-up to a trailer hitch. The Brafford patent differs in that the main objective is a lighted display sign that uses light bulbs for sign viewing. It provides a protective cover that prevents damage by weather and exposure.

[0010] U.S. Pat. No. 6,007,033 to Casson et al. describes a placard or brake light installed into the hitch. U.S. Pat. No. 6,053,627 to Vo describes a cover that blocks the hitching socket from view in a decorative manner. U.S. Pat. No. 6,079,136 Kozlarek relates to a display that employs a message systems. The signal and brake lights are small and are housed inside the display unit. The signals are located behind the message display and this limits the illumination for the signal.

[0011] U.S. Pat. No. 5,829,774 to Klemp describes a bumper with signaling brake lights that are housed in the same unit. Klemp does not have the ability to have a usable step bumper. U.S. Pat. No. 6,015,223 to Kidd and Filbrun describes a light carrier with light emitting diodes in a lens carrier that is meant to be seen when other brake lights are obscured to following vehicles that are behind.

[0012] U.S. Pat. No. 6,302,567B1 to Gamble describes a removable and vertically adjustable warning light attached into the hitch to warn other vehicles. U.S. Pat. No. 6,140,919 to Buchanan shows an auxiliary signal light system's enhancements that are arranged in a radial fashion. The signal lights are housed in the arms and brake light attachments in the well of the housing. The turning signals are formed in the surface of the arms.

[0013] U.S. Pat. No. 6,357,899 to Craven describes a type of trailer hitch cover with a decorative logo on a lens face. U.S. Pat. No. 6,379,028B1 to Crouse refers to plastic light partial shell assembly with clear lenses adapted to receive various indicia for illumination beyond the rear of the vehicle that provides supplemental back-up lighting.

[0014] U.S. Pat. No. 6,412,202B1 to Oswood describes a signage patent for messages with clips on the tongue. U.S. 6,413,101 to Divoll describes a power outlet adapter that lacks being placed on a light bar. U.S. Pat. No. D437,431S to Crouse covers design patterns for the partial shells assembly.

[0015] U.S. Pat. No. 6,491,315 to Hagen describes a brake warning and step for a bumper and a warning brake light and signal light. U.S. Pat. No. 6,553,697B1 to Pichan describes a lighted sign having readily attachable/detachable display panels. Inside this housing are signal and brake lights. U.S. Pat. No. 2003/0011164 A1 to Cipolla describes a metal collar configured to the same shape as the squared male joining member of the hitch. The collar was used to quite vibrations from the hitch coupling by mechanically tightening the collar. Plastic is used to coat the metal collar so that the hitch would not be unnecessarily scraped up while in use.

[0016] U.S. Pat. No. WO 000/15975 to Daudi describes a viscoelastic adhesive bonded to an intermediate element reducing vibration and noise on the friction rings consisting of “any adhesive having viscous properties and elastic properties and having a greater tendency for reducing the transmission of vibrations.” Silicone is the preferable adhesive. The adhesive with intermediate laminate metal such as steel or a laminate fiber reinforced with plastic is used for the element to reduce vibration or noise. In contrast, the plastic in the present invention is a flexible solid, e.g., not like the Daudi patent of viscous silicon that become non-flexible when used with metals and incorporated in layers that become more rigid.

[0017] U.S. Pat. No. 2003/0172498 to Polzin et al. describes a cushion made of polymers that have a new layer of foam or foaming materials that accomplish vibration damping to a user. This varies from the slidable non-friction material of this patent by utilizing a foaming or foam agent to produce honeycomb cells compressing under a users grip for cushioning purposes. The entirety of each of the aforementioned U.S. patent Documents is hereby incorporated by reference.

[0018] The present inventor has determined that the previous systems lack a full functioning wiring harness equipped with driving, back-up, marker, signaling, brakes, signals, hazard, strobe, marker, fog and illuminating lights. The light bar unit of the present invention has the option of add-ons such as extension bars equipped with lights, lockable protective covers, protection coatings or external electrical plug-in sockets. The ability to store that “extra set of keys” in a hide-way lockable compartment is another safety feature. The plastics in the collars or strips are used to facilitate the telescoping ability of the couplings. The collars or strips possess the ability to lower the noise or vibration level on the interior of the female coupling, on the male coupling, other positions on the couplings or orifices.

[0019] The safety bar equips the vehicle with an integrated light system that utilizes a harness assembly that contains driving, brake/signal, flasher/emergency, back-up, strobe, marker, fog and/or illuminating lights. The wiring harness assembly is equipped to use the most common standard flat 4-way plug or a combination plug system made to conform to an individual light bar unit. The wiring harness assembly contains the same number of wires and the placement of these wires matches the number of light fixture units in a light bar unit. The present invention relates to a light bar unit that encompasses the entire width of the vehicle and is connected beneath their existing bumpers. Vehicles and their respective bumpers vary in size and width and depth. The present invention varies in size and width to compliment the bumpers.

[0020] The National Highway Traffic Safety Administration states that millions of traffic accidents can be reduced by half by introducing supplementary lighting on the rear portion of vehicles. This novel light bar unit provides a method and the means to enhance safety, by utilizing the light bar units functions, giving greater visibility while driving or at rest. A traffic accident may involve vehicles running or parking in the dark, dim, dusky, foggy or even daytime lighting. Incorrectly judging the distance, the operator does not estimate the distance the vehicles are apart. The use of trucks has increased the number of trailers to pull such items as: snowmobiles, boats, camping equipment, pop-up tents, motorcycles and horse trailers. Most vehicles are purchased with hitches that are located under the bumper and others are installed with after-market hitches.

[0021] The present invention overcomes the shortcomings associated with the background art and achieves other advantages not realized by the background art.

[0022] An object of the present invention is to provide a novel safety light bar signal combination (light bar unit) and method that has many advantages over the background art.

[0023] Most vehicles are now purchased with hitches. Many other vehicles have after-market hitches installed because of the expanded market for trailers, boats, and numerous other items being towed on today's highways.

[0024] For vehicles especially those currently operating on the highways and roads, the device provides a method to enhance safety. The advantages in safety are significant in that added light gives the operator greater visibility that is highly desirable. By utilizing the light bar lens assembly that functionally gives a vehicle greater visibility it enhances safety while driving or at rest.

[0025] The ability to connect your trailer system above the light bar unit has another feature that benefits the vehicle owner. It keeps the wires and the electrical connectors running between the vehicle and the light bar unit in the shortest possible length for purposes of safety and convenience. The wiring harness assembly exits the rear of a vehicle and then the end of the electrical plug-in socket can be hooked up to the hitches electrical connections. Another way to hook up exterior elements is to duplicate the electrical plug-in sockets and have two separate wiring units running between the vehicle and the trailer system. It becomes clumsy and disorganized and must be removed when the extra wiring for the trailer is not in use. This causes the owner to remove the extra electrical plug-in sockets numerous times if the owner plans to utilize the vehicle and trailer system.

[0026] The present inventor has determined that there is a need for a device that can be used for a light bar unit that can accommodate lower profile vehicles. The back plate is positioned and attached centrally or offset to the light bar housing either on the upper section or on the lower section of the light bar housing. When attaching the light bar housing to a vehicle, it can be inverted with the offset placement of the back plate. This allows the light bar unit to have a lower profile under the lower profile vehicle bumper. The lower position enables the light bar unit to clear obstacles such as license plates, bumpers and exhaust pipes. In many cases, the vehicle would not otherwise have been able to accommodate the light bar unit. The light bar unit can also be attached or mounted to other vehicles, trailers, off road farm vehicles or farm equipment. The method for attaching or mounting the light bar includes bolts, screws or hooks and other normal attaching or mounting means and materials. The mounting hardware can be attached to any surface (front side, backside or two side surfaces) of the light bar unit to accomplish the mounting process.

[0027] The ability to connect an additional trailer system into the light bar unit is another feature that benefits the vehicle owner. Keeping the wires and the electrical plug-in sockets running between the vehicle and a trailer organized and compact adds safety and convenience.

[0028] Trailers and other towable apparatus that are inserted into hitches have undesirable side effects of vibrations, rattles and noise when towed. Collars/strips attached to the light bar unit help limit vibrations or noise of the coupling or openings. By keeping distractions to a minimum for operators, the vehicle's safety is enhanced. Collars/strips of friction reducing materials are attached onto the hitch components, e.g., the exterior of the male tongue insert (located on the light bars) or the interior cavities of the female receiving socket (located on vehicles).

[0029] Protective covers are produced for the light bar units and comprises from various lightweight or ridged materials that can be used to produce the protective cover. The cover protects the light bar unit from various types of damage. Conventional or flexible materials that can fit snugly over the light bar unit form a cover for protection from dust or dirt and the protective cover is lockable to prevent vandalism or theft.

[0030] One or more of these and other objects is accomplished by a safety light bar capable of being inserted into a mounting hitch comprising a light bar housing having peripheral walls including a top and bottom surface, a vertical side surface and an opposing side surface that collectively form a cavity inside the light bar housing; a light fixture assembly mounted within the light bar housing; a fastening device for affixing the light bar housing to a mounting surface; and an electric plug connector connecting the light fixture assembly mounted into the light bar housing to a power source.
