PRIOR HISTORY  
      This application is a continuation-in-part patent application claiming the benefit of pending non-provisional U.S. patent application Ser. No. 11/062,727, filed in the United States Patent and Trademark Office on Feb. 22, 2005, which application is a non-provisional patent application claiming priority to provisional U.S. Patent Application No. 60/588,324, filed in the United States Patent and Trademark Office on Jul. 16, 2004. 
    
    
     BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention generally relates to vehicular traffic safety devices. More particularly, the present invention relates to vehicular traffic signaling lights and signs and specifically discloses a traffic control sign assembly.  
      2. Description of the Related Art  
      Traffic control devices have been used in many applications for decades. Such devices range from hand-held signs to traffic signs and lights. Applications vary and include school crossings, construction sites, airports, roadside emergencies, trucking usages, emergency equipment and so forth. These devices are used to alert the public and oncoming traffic of potential safety issues and are also used to protect those located at the locations at issue. Many devices have been prepared and used for these applications; however none of these devices, to the knowledge of the inventors, provide protection and warning to oncoming traffic at such distance and with such coverage as with the present invention hereafter disclosed.  
      Existing devices, such as the Illuminated Traffic Sign of U.S. Pat. No. 6,198,410 B1, which issued to White et al., disclose an illuminatable traffic sign that is secured to a post and has indicia disposed thereon and a plurality of lights positioned along an outer periphery and along the indicia. However, the White apparatus does not appear to teach the light enhancement and coverage concepts of the present invention and the lights used in the White apparatus only appear to be as effective as their individual wattages.  
      In like manner, U.S. Pat. No. 6,029,382 which issued to Kochanowski, discloses a Reflective Sign that includes a face member that has a plurality of cube corners disposed along a back surface for light reflection. However, the &#39;382 device relies upon reflection of oncoming light and does not provide an enhanced lighted sign assembly that can be seen at dusk or night without the use of lights in oncoming vehicles, flashlights, and the like.  
      Other patented sign devices including those of U.S. Pat. Nos. 6,009,650; 6,422,714 B1; 5,276,424; 6,409,358 B1; 6,407,675 B1; and 6,239,691 B1 provided lighted sign devices. However, none provide the enhanced visual clarity, brightness, and coverage features needed to warn oncoming traffic and the public from distances as far away as ¼ mile and in a 170 degree line of sight from the center of the sign. It is therefore important and necessary that a traffic control sign assembly be developed that provides enhanced visual clarity, brightness, and coverage including up to distances of at least ¼ mile and at nearly any angle from which the sign can be turned. The traffic control sign assembly must be highly visible, distinctly display the appropriate warning messages, capable of quickly being powered by various means, sturdy, lightweight, adaptable to different sites and under different working conditions, and be easy to use and manufacture.  
      Other objects of my invention, as well as particular features, elements, and advantages thereof, will be elucidated in, or apparent from, the following description and the accompanying drawing figures.  
     SUMMARY OF THE INVENTION  
      The present invention provides a vehicle signal light assembly comprising a two-sided sign assembly composed of cooperatively opposite sign structures each having a central opening defined therein, an inner sign structure surface, and an outer sign structure surface. The central openings are defined by a light panel-receiving framework at the inner sign structure surfaces and by opposed diffusing panel-receiving frameworks at the outer sign structure surfaces. The light panel-receiving framework frames a two-sided light emitting diode (LED) light panel, the LED lights of which are exposed by the central opening. The light panel is thus sandwiched between the cooperating sign structures within the light panel-receiving framework. Light diffusing panels are received in the opposing diffusing panel-receiving frameworks. Light emitting from the LED&#39;s thus passes through the central opening and is diffused by the opposed light diffusing panels.  
      The light panel is powered by a power source such as electrochemical batteries, which batteries are located in inferior adjacency to the sign structures. Switch means selectively enable the user to power the light panel and optionally may function to provide a constant power source (for providing a constant illuminated signal) or to provide a periodic power source (for providing a flashing illuminated signal). Further, fastening means function to connect the sign structures to each other in unitary assembly.  
      A legend-bearing screen or sign is positioned intermediate each light diffusing panel and the light panel, each of which bear a traffic control signifier, such as “STOP” or “SLOW”. A handle assembly may be secured to the outer perimeter of the sign structures for enabling the traffic control sign assembly to be hand held by a person.  
      In another embodiment, a vehicle signal light assembly is provided, which vehicle signal light assembly is designed to be hand held, pole (telescopically) assisted, or hands-free stand-mounted, and comprises a flat plate sized and shaped in the form of a traffic sign that has a central opening defined by an annular sign rim. A control console structure is secured in centered relation in said central opening and is peripherally bounded by said annular rim. A two-sided bread board type LED light panel is mounted in said control console structure and diffused or prismatic panels are mounted on opposite sides of said control console structure on opposite sides of said central opening. Batteries are mounted on an underside of said control console structure and are connected to said two-sided bread board type LED light panel thus providing electrical power to light said two-sided bread board type LED light panel. Means connecting said control console structure internally and to said sign in unitary assembly are provided. A first silk screen with a traffic legend on back of one of said diffused or prismatic panels is mounted in said control console structure while a second silk screen with another traffic legend on back of another of said diffused or prismatic panels is mounted on an opposite side of said control console structure. Switch means for turning said batteries “ON” in a holding or a flashing mode and for turning said batteries “OFF” is also provided.  
      In still another embodiment, the present invention provides a traffic control sign assembly comprising a sign having a central opening defining an annular sign rim and opposing sides. A control console is positioned on each opposing side of said sign in centered relation to said central opening and means connecting said control consoles to said sign and to each other in unitary assembly are provided. A double-sided light panel (optionally mirrored) having LED&#39;s is mounted on opposing surfaces and is centrally located in said connected control consoles. A prismatic panel is centrally mounted in each control console over each opposing surface of said optionally mirrored double-sided LED light panel and said central opening. A power source is electrically connected to said double-sided LED light panel and a handle assembly is secured to said sign for supporting said sign.  
      Finally, in another embodiment, the present invention provides a traffic control sign assembly kit. The kit essentially comprises: a traffic sign (assembly); a modular handle assembly or telescoping pole assembly; a power source (e.g. batteries, an inverter and cord, vehicular cigarette lighter cord, external battery cord); various accessories; and a carrying case. Said traffic sign assembly comprises a traffic sign having a central opening defining an annular sign rim and opposing sides. A control console is positioned on each opposing side of said traffic sign in centered relation to said central opening. Means connecting said control consoles to said traffic sign and to each other in unitary assembly are provided. A dual-sided LED light panel (optionally mirrored) is centrally located within said connected control consoles and a prismatic panel is centrally mounted in each control console over the optionally mirrored, dual-sided LED light panel and the central opening. The power source is electrically connected to the optionally mirrored LED light panel and the modular handle or telescopic pole assembly and includes screwed-in attachment means for constructing and for securing the modular handle or telescopic pole assembly to itself and to said traffic sign. The carrying case is provided for containing the traffic sign (assembly); the modular handle assembly or telescoping pole assembly; the power source (e.g. batteries, an inverter and cord, vehicular cigarette lighter cord, external battery cord); and various other accessories as may be required.  
      The present invention therefore provides a traffic control sign assembly that provides enhanced visual clarity, brightness, and coverage including distances of at least ¼ mile and at nearly any angle from which the sign can be turned. The traffic control sign assembly is highly visible, distinctly displays the appropriate warning messages, is capable of quickly being powered by various means and is sturdy, lightweight, adaptable to different sites and under different working conditions, and is easy to use and manufacture.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)  
      Referring now to the drawings, the present invention concerns a traffic control sign assembly, also known as a traffic control sign assembly or a vehicle signal light assembly. A preferred embodiment of the traffic control sign assembly is illustrated and generally referenced at  10  in  FIGS. 1, 2 ,  22 , and  23 . A preferred alternative embodiment of the traffic control sign assembly is illustrated and generally referenced at  80  in  FIGS. 24-28 . It is contemplated that traffic control sign assemblies  10  and  80  are to be particularly used in various settings and circumstances to warn oncoming motorists and people of safety and emergency issues. In this last regard, by way of example, it is contemplated that traffic control sign assemblies  10  and/or  80  may be used in situational scenarios such as at school, construction, industrial, fire safety, law enforcement, and at emergency sites. As previously discussed above under the section entitled, BACKGROUND OF THE INVENTION, from a safety standpoint, it is very important to provide a traffic control sign assembly that provides enhanced visual clarity, brightness, and coverage including distances of at least ¼ mile and at nearly any angle from which the sign can be turned. Thus, it is contemplated that traffic control sign assemblies  10  and/or  80  must be highly visible, distinctly display the appropriate warning messages, be capable of quickly being powered by various means, be sturdy, lightweight, adaptable to different sites and under different working conditions, and be easy to use and manufacture. The present invention as embodied in traffic control sign assemblies  10  and/or  80  provides these key features and further satisfies these needs. It is not intended that the present invention be limited solely to the specifics disclosed, rather it is intended that the scope of the present invention also include other traffic control sign devices and the like.  
      A first preferred embodiment of the present invention is illustrated in  FIGS. 1 and 2 , namely, a traffic control sign assembly  10  or vehicle signal light assembly. It will be seen from an inspection of  FIGS. 1 and 22  that (glass bead type) reflective tape  5  can be mounted on edges of both sides of said traffic sign for increased visibility of said traffic sign. Traffic control sign assembly  10  preferably comprises a sign  11  as is illustrated and referenced in  FIGS. 1-4 ,  9 - 13 ,  15 ,  15 ( a ),  15 ( b ),  16 , and  17 ; a pair of control consoles  12  as illustrated and referenced in  FIGS. 1, 2 ,  5 ,  6 ,  9 - 15 ( b ),  16 , and  17 ; a two-sided bread board type LED light panel  13  as illustrated and referenced in FIGS.  2 ,  7 ( b ),  8 ( b ),  12 ,  13 ,  25 , and  27 ; light-diffusing (diffused or prismatic) panels  14  as illustrated and referenced in FIGS.  2 ,  7 ( a ),  7 ( c ),  8 ( a ),  8 ( c ),  14 ,  24 ,  25 , and  27 ; batteries  15  as illustrated and referenced in FIGS.  15 ( c ) and  19 ; means connecting control consoles  12  to sign  11  and each other in unitary assembly; first and second silk screens  20  as illustrated and referenced in  FIG. 14 ; switch means; and a handle assembly  16  as generally illustrated and referenced in FIGS.  1 ,  9 - 12 ,  15 ,  15 ( a ),  24 - 28 , and  30 .  
      Sign  11  preferably comprises a central opening  17  as generally referenced in  FIGS. 2 and 3 . It will be understood from an inspection of the noted figures that central opening  17  is preferably defined by an annular sign rim. It will be further understood from a consideration of the noted figures that control consoles  12  are preferably positioned on opposite sides of sign  11  and are preferably in centered relation to central opening  17 . Light panel  13  is preferably mounted in central opening  17  in sandwiched relation between control consoles  12 . Diffused or prismatic panels  14  are preferably mounted in control consoles  12  in central alignment on opposite sides of central opening  17 . Batteries  15  are preferably mounted on an underside of control consoles  12  and connected to two-sided bread board type LED light panel  13 , thus providing electrical power to light two-sided bread board type LED light panel  13 . The means connecting control consoles  12  to sign  11  and each other in unitary assembly may preferably be defined by rivets  18  and rivet-receiving structure  19  as both are illustrated and referenced in  FIG. 2 . Rivets  18  are further referenced in  FIGS. 12-15 ,  16  (6 rivets  18 ), and  17 . Rivet-receiving structures (apertures)  19  are further referenced in  FIGS. 5 and 17 . It will be seen from a comparative inspection of the noted figures that the number of rivets  18  and corresponding rivet-receiving structures  19  may vary depending on the application.  
      In one embodiment, first silk screen  20  bearing the legend “STOP” appears on back of one of diffused or prismatic panels  14  is mounted in one of control consoles  12  and second silk screen  20  with bearing the legend “STOP” or “SLOW” appears on back of another of diffused or prismatic panels  14  mounted in another of control consoles  12 . The switch means, designed for turning batteries  15  “ON” in a holding or a flashing mode and for turning batteries  15  “OFF” have been generally referenced at  21  in FIGS.  15 ,  15 ( a ), and  15 ( b ). Handle assembly  16  is preferably secured to sign  11  for enabling sign  11  to be hand held by a person.  
      Thus, traffic control sign assembly  10  preferably comprises sign  11  having central opening  17  that is defined by an annular sign rim. Sign  11  can be octagon shaped, such as for a standard stop sign, as has been generally illustrated in the noted figures for ease of illustration, or sign  11  can be shaped as deemed necessary, it being noted that signs take on various shapes and sizes. In addition, sign  11  can be painted with reflective paint or have reflective tape, such as glass bead type reflective tape, attached to its surface and edges to enhance the display of the message. For example, a red color can be used for a “STOP” message and orange for “SLOW” and these colors can be painted to conform with standard shapes as used in traffic laws, such as octagonal for stop and triangular for yield and so forth. Moreover, sign  11  may be silk screened to enhance the messages displayed and the size and presentation of the sign is intended to meet all federal, state, and local codes. It is also intended that these features apply to both sides of sign  11  as it is dual-sided as explained in more detail below.  
      The pair of control consoles  12  is preferably positioned on opposite sides of sign  11  and in centered relation to central opening  17 . Control consoles  12  are central to housing certain lights and circuitry of the present invention. It is contemplated that control consoles  12 , and other parts to this invention are constructed of light-weight plastic, such as standard ABS, using injection or vacuum molding processes as are standard in the industry. Moreover, these and other parts are light-weight and the traffic control sign assembly  10  itself is intended to weigh approximately 5 pounds or less including batteries  15  and the like so that it may be easily held or supported by a person.  
      A further key feature of the present invention is two-sided bread board type LED light panel  13 . Light panel  13  is preferably mounted in central opening  17  in sandwiched relation between control consoles  12 . Light panel  13  is preferably a rectangular-shaped, double-sided, printed circuit board. Optionally, light panel  13  may comprise or be constructed of a mirror type material so as to increase its brightness and reflection capabilities. Light panel  13  is also known in the art as a bread board. In one embodiment, light panel  13  comprises LED lights  22  as illustrated and referenced in  FIGS. 2, 7 ,  8 ,  12 ,  13 ,  14 , and  19 . LED lights  22  are preferably placed or surface mounted upon the circuit board to form or print the message that traffic control sign assembly  10  will state to oncoming traffic and people. LED lights  22  are preferably high-intensity lights and may be colored as deemed effective for the usage and situation. In a preferred embodiment, LED lights  22  are placed on each side of light panel  13  to form a legend or message on each side of light panel  13  so that an appropriate traffic control message will be communicated simultaneously to oncoming traffic on both sides of traffic control sign assembly  10 . In a preferred embodiment, the legend(s), message(s), or advisories printed by LED lights  22  is/are “STOP” and “SLOW” as may be seen from a general inspection of  FIG. 7 . In this last regard, it is contemplated that traffic control sign assembly  10  may either state (on opposite assembly sides) “STOP-STOP” (as is generally depicted in  FIG. 8 ) or “STOP-SLOW” for safety and traffic control purposes, such as would be the case at an accident, in construction zones, or at a school crossing scene.  
       FIG. 20 ( a ) depicts a further rendering of a “STOP-STOP” advisory;  FIG. 20 ( b ) depicts a further rendering of a “STOP-SLOW” advisory; and  FIG. 20 ( c ) depicts a rendering of a “SLOW-SLOW” advisory, all of which advisories represent common or typical advisories. It is contemplated that other advisories may easily be rendered upon the sign with appropriate adjustments. It will be seen from an inspection of FIGS.  20 ( a ) through  20 ( c ), that the present invention may further comprise reflective materials (paint or tape)  40  formed adjacent LED lights  22  so that a reflective material advisory appears in tandem with the LED light advisory. LED lights  22  are designed to shine through round apertures  41  as further referenced in  FIGS. 1 , and  20 ( a ) through  20 ( c ). It will thus be understood that advisories or legends may be painted with reflective materials with round apertures  41  for allowing light emanating from LED lights  22  to pass therethrough. Thus, the user may provide warnings or advisories even if the LED lighting turned off or otherwise inoperative. Reflective materials  40  and round apertures  41  are further illustrated and referenced in  FIG. 22 .  
      In other embodiments, light panel  13  could include a plurality of LED lights  22  and could be programmable so that the message(s) programmed will light up only the appropriate LED lights  22  to display the message. For illustration purposes only, the word, “STOP” uses 57 pixels and the word “SLOW” uses 63 pixels—the number of pixels varying depending upon the diameter of the pixels. Moreover, in particular where the messages are programmed, an additional feature is a microprocessor chip capable of holding messages in memory to preserve messages and/or to continue to display messages on traffic control sign assembly  10  even when the main power source (i.e. battery  15  and the like) expire.  
      Other key features of the present invention are diffused or prismatic panels  14 , or prismatic panels as they are known in other embodiments. Diffused or prismatic panels  14  are preferably mounted in each control console  12  in central alignment on opposite sides of central opening  17 . Diffused or prismatic panels  14  are preferably prismatic, meaning that they spread or diffuse light energy. Diffused or prismatic panels  14  thus preferably provide a cover for one side of the respective control console  12  and two-sided bread board type LED light panel  13 .  
      In a preferred embodiment, first silk screen  20  bears the legend “STOP” and is located on the back of one of diffused or prismatic panels  14 ; further, second silk screen  20  bears the either the legend “STOP” or the legend “SLOW” and is located on the back of the other of diffused or prismatic panels  14 . These silk screen legends are then aligned with LED lights  22  so that the spread of the light thereby increases the brightness and clarity of the message. The alignment and usage of the diffused (prismatic) panels  14  increases the distance from which the message can be easily read at least ¼ mile from traffic control sign assembly  10  and the angle of view of light panel  13  so that the message can be read from up to a 170 degree line of sight from the center of sign  11 .  
      The ability to read the message from practically any orientation of traffic control sign assembly  10  dramatically increases the effectiveness of traffic control sign assembly  10  and practically overcomes any error in orientation of traffic control sign assembly  10  in the field, such as when the holder has accidentally turned planar portions of traffic control sign assembly  10  somewhat away from oncoming traffic. As discussed above, the messages on both sides of traffic control sign assembly  10  can then be read and understood at nearly all angles and from a large distance, thus improving protection of both the reader and the holder and people at the site at issue. Diffused or prismatic panels  14  are preferably constructed from phenolic type material (i.e. a type of reflective sheet covering) including pyramid type cones (i.e. dimpled) upon a surface thereof to deflect the light in all directions and to spread the light to enhance and equalize the brightness within the “pixel-looking” circles.  
      A power source, such as batteries  15  in a preferred embodiment, are mounted (i.e. preferably horizontally) on an underside of control consoles  12  in battery or power source compartments  23  as are illustrated and referenced in FIGS.  1 ,  9 - 13 , and  15 - 15 ( c ) and are connected to two-sided bread board type LED light panel  13  for providing electrical power to light two-sided bread board type LED light panel  13 . In addition, it is contemplated that a low battery sound indicator  24  as referenced in  FIG. 19  and automatic shut-off/shut-down of two-sided bread board type LED light panel  13  are provided as added features of the present invention. It is contemplated that other power sources, such as solar power and external power, may be utilized to power certain electric circuitry contained in traffic control sign assembly  10 .  
      For example, it is contemplated that the present invention provides means for converting and using power from a source such as the cigarette lighter of any vehicle (e.g. an emergency vehicle) using a standard power inverter or from an external battery pack, which pack may be included in a traffic control sign assembly kit, as described in more detail hereinafter. In addition, the battery-powered power source can include battery packs (i.e. venus type), the preferred embodiment being two D-size cell battery packs with one pack for each side of the LED lights, and other larger 8-battery packs being used to increase battery life for traffic control sign assembly  10 . The battery pack can also be recharged whether by direct plug-in cord adaptor with standard voltage ratings or by removal of the battery pack from traffic control sign assembly  10  and placement on a standard charger.  
      It should be noted (by way of example) that the control console may be plugged into any of the following external power sources: any vehicular cigarette lighter (12V direct current) by utilizing a power converter assembly (provided separately or provided with the traffic control sign assembly kit); any vehicle with a generator (e.g. emergency vehicles) supplying alternate current by utilizing a power inverter assembly (provided separately or provided with the traffic control sign assembly kit); or a standard external battery pack consisting of up to 16 batteries for longer life of LED lights  22 .  
      As earlier stated, in order to make traffic control sign assembly  10  sturdy and practical for field use, the present invention makes use of means for connecting control consoles  12  to sign  11  and each other in unitary assembly. Said means may be further defined by comprising silicone glue fastening means  25  (referenced in  FIG. 14 ) so as to keep components from “shearing off” if traffic control sign assembly  10  is otherwise dropped or jarred and further for keeping the unit water tight and usable in all weather conditions. In other words, it is contemplated that the silicone adhesive, having shock absorbing and weather barrier type properties may effectively function to prevent damage to components experiencing rapid accelerative forces (as by being dropped or jarred) and for enabling use of the vehicle signal light assembly in all weather conditions (as during rainy conditions).  
      In addition, various spacers, insulating materials, connectors and standoffs are used as needed. In this regard, it is contemplated that a rubber type edge molding  26  is placed around the entire light panel  13  prior to insertion into central opening  17  to strengthen the attachment therein and to secure light panel  13  in case traffic control sign assembly  10  is bumped or dropped. Edge molding  26  is illustrated and referenced in  FIGS. 2, 12 ,  13 , and  18 .  
      Another important feature of the present invention is switch means, shown at  21  in  FIGS. 15 and 15 ( a ), preferably defined by three-way selector switch means in a preferred embodiment. The switch means operate to activate the power source between “OFF”, continuous on, and flashing sequence modes so that the power source can then operate each set LED lights  22  on the opposing surfaces of traffic control sign assembly  10  independently and in any of the various modes. A preferred flashing sequence includes five flashes of LED lights  22  followed by 2 to 15 seconds where LED lights  22  are continuously on. Other flashing sequences can be programmed as needed. A generalized circuitry drawing is included as  FIG. 19 . The continuous ON and flashing modes, for example, coact with the diffused or prismatic panel structure so as to enable traffic control sign assembly  10  to be seen up to over ¼ of a mile before the headlights of on-coming vehicles hit the standard reflective signs and to give the holder of traffic control sign assembly  10  far greater safety in being seen. In another embodiment, the present invention also contemplates the usage of a strobe light located atop the sign for additional protection of the user and to draw further attention to the message.  
      An additional significant feature of the present invention, as generally referenced in  FIGS. 9-12 ,  15 , and  15 ( a ), is handle assembly  16 . Handle assembly  16  is preferably secured to sign  11  for enabling traffic control sign assembly  10  to be hand held by a person, in a preferred embodiment. Handle assembly  16  preferably includes different embodiments including a telescoping handle  27  as illustrated and referenced in FIGS.  15 ,  15 ( a ),  25 , and  30 . Handle  27  preferably comprises screw means for screwed-in attachment and detachment means, a collapsible tripod embodiment for hands-free use, a modular or multi-sectioned handle that has screw attachment means, and a weighted base self-supporting stanchion embodiment that rests upon the ground. Handle assembly  16  may further preferably comprise a slide-on grip  28  as illustrated and referenced in  FIGS. 9, 10 ,  11 ,  15 , and  15 ( a ) and telescoping handle  27  can extend traffic control sign assembly  10  to over 6 feet high for better message visibility. Handle assembly  16  may preferably be constructed from wood, plastic, or metal materials, and may be slotted so as to be received and yoked or interlocked with the sign. It should be noted that handle assembly  16  should be of sufficient weight so that traffic control sign assembly  10 , in total, weigh approximately 5 pounds or less. Although not shown, other usages contemplated for the sign can include attachment to vehicles, such as school buses.  
      Further, it is contemplated that a hands-free, stand-mounted traffic control sign assembly  50  (as may be seen from an inspection of  FIG. 21 ) may enable the user to temporarily situate the sign assembly so that the user may be free to perform other activities (other than holding sign assembly  10 ). From an inspection of  FIG. 21 , it will be seen that stand-mounted traffic control sign assembly  50  preferably comprises sign  11 ; a threaded sleeve  51 ; a locking knob  52 ; a tripod or four-legged stand  53 ; and a telescoping pole  54 . Threaded sleeve  51  threads up onto base of the handle. The tripod or four-legged stand  53  may preferably comprise foldable legs  55  for portability. Telescoping pole  54  is designed for height adjustment as does locking knob  52 . Note that the same telescoping pole may be utilized for the hand-held traffic control sign assembly or the stand-mounted traffic control sign assembly. With regard to the hand-held version, it is contemplated that a grip  6  (as referenced in  FIGS. 1, 22 , and  24 - 28 ) may be utilized in combination with handle assembly  16  to provide the holder with more comfortable structure with which to grasp and hold traffic control sign assembly  10 .  
       FIG. 23  is a fragmentary bottom perspective view of traffic control sign assembly  10  showing switch means  60  and low battery alert means  70 . Low battery alert means  70  may be defined by electronically enabled audio means for alerting users to a low battery power state or visual means for alerting users to a low battery power state. Switch means  60  function to provide an OFF, an ON, or a FLASHING (i.e. alternating OFF-ON) LED light condition as desired by the user. It is contemplated that switch means  60  and low-battery alert means  70  are preferably located on the underside or inferior side of one control console  12  with enabling circuitry disposed internal to the sign assembly.  
      Finally, in another embodiment, a traffic control sign assembly kit is provided. As earlier indicated, the kit essentially comprises: a traffic sign (assembly); a modular handle assembly or telescoping pole assembly; a power source (e.g. batteries, an inverter and cord, vehicular cigarette lighter cord, external battery cord); various accessories; and a carrying case. Thus, the kit preferably comprises sign  11 ; modular handle assembly or telescoping pole assembly  16 ; a power source; and a carrying case (not specifically illustrated). Traffic sign  11 , as described above, comprises central opening  17  defining an annular sign rim and opposing sides; control consoles  12  may be positioned on each opposing side of traffic sign  11  in centered relation to central opening  17 ; means connecting control consoles  12  to traffic sign  11  and to each other in unitary assembly; an optionally mirrored, dual-sided LED light panel  13  centrally located within the connected control consoles  12 ; and a prismatic panel  14  centrally mounted in each control console  12  over the optionally mirrored, dual-sided LED light panel  13  and central opening  17 . The power source is electrically connected to the optionally mirrored LED light panel  13  and modular handle assembly  16 , which assembly  16  includes screwed-in attachment means for constructing and for securing modular handle assembly  16  to itself and to traffic sign  11 . The carrying case is provided for containing the traffic sign (assembly); the modular handle assembly or telescoping pole assembly; the power source (e.g. batteries, an inverter and cord, vehicular cigarette lighter cord, external battery cord); and various other accessories as may be required. The carrying case is sized for carrying traffic sign  11 , the power source, and modular handle assembly or telescopic pole assembly  16  in detached form and is preferably constructed of vinyl or plastic materials.  
      In construction and in use the present invention therefore provides traffic control sign assembly  10  that provides enhanced visual clarity, brightness, and coverage including up to distances of at least ¼ mile and at nearly any angle from which traffic control sign assembly  10  can be turned. Traffic control sign assembly  10  is highly visible, distinctly displays the appropriate warning messages, is capable of quickly being powered by various means, and is sturdy, lightweight, adaptable to different sites and under different working conditions, and is easy to use and manufacture.  
     PREFERRED ALTERNATIVE EMBODIMENT(S)  
      It is further contemplated that in one alternative embodiment, two-sided bread board type LED light panel  13  may be replaced by two bread board type LED panels  13 ( a ), each of which may be attached to the alternative traffic control sign assembly by being received in the space  29  of control console  12 , which space  29  is generally referenced in  FIGS. 6 and 14 . From an inspection of  FIG. 14 , it will be seen that it is contemplated that silicone glue fastening means  25  may be sandwiched by light panel  13 ( a ) and sign attachment structure  30  of each control console  12 . It will thus be understood from an inspection of  FIG. 14  that alternative sign  11 ( a ) is mostly continuous, not comprising central opening  17 , but perhaps comprising rivet-receiving structure  19  as may be further gleaned from an inspection of  FIG. 14 .  
      Further, as preliminarily addressed hereinabove, a preferred alternative embodiment of the present invention is generally illustrated in  FIGS. 24-28 , namely, a traffic control sign assembly  80  or vehicle signal light assembly. Traffic control sign assembly  80  differs from traffic control sign assembly  10  primarily in that the separately formed control console assembly (comprising two control consoles  12 ) of traffic control sign assembly  10  are made integral with the sign structure, which sign structure has been divided into two opposing pieces, each piece essentially comprising an integral control console. It is contemplated that two sign structures each formed with an integral control console as in traffic control sign assembly  80  may be less costly to manufacture than sign  11  and two control consoles  12  to from traffic control sign assembly  10 . Further, it is contemplated that traffic control sign assembly  80  may be less weighty and thus require less force to support for the benefit of oncoming traffic and the like.  
      Thus, it will be seen that two-sided traffic control sign assembly  80  preferably comprises two opposing sign structures  81  as is illustrated and referenced in  FIGS. 24-28 ; two-sided bread board type LED light panel  13  (as further referenced in  FIGS. 25 and 27 ); a first legend bearing screen  82  as illustrated and referenced in  FIGS. 25, 27 , and  28 ; a second legend bearing screen  83  as illustrated and referenced in  FIGS. 25-27 ; light-diffusing (diffused or prismatic) panels  14  (as further referenced in  FIGS. 24, 25 , and  27 ); two opposing display guards  84  as illustrated and referenced in  FIGS. 25-28 ; and a power source, such as batteries  15 , as housed within a battery pack  85  (referenced in  FIGS. 25 and 29 ), which battery pack  85  is receivable in a battery box  86  as referenced in  FIG. 25 . Traffic control sign assembly  80  further comprises handle assembly  16  as further referenced in  FIGS. 24-28 , and  30 , which handle assembly preferably comprises hand grip  6  as further referenced in  FIGS. 24-28 . Further, certain means for connecting sign structures  81  to one another; for connecting display guards  84  to sign structures  81 ; and for connecting handle assembly  16  to sign structures  81  are contemplated. Certain switch means are further generally illustrated and referenced at  87  in  FIGS. 25 and 30 .  
      Each sign structure  81  preferably comprise a central opening  88  as generally referenced in  FIGS. 25 and 27 ; an inner sign surface  101  as referenced in  FIGS. 24, 25 , and  27 ; and an outer sign surface  102  as referenced in  FIGS. 24-28 . It will be understood from an inspection of the noted figures that each central opening  88  is preferably defined by cooperative light panel-receiving frame structure(s) at the inner sign surfaces  101 , and by cooperative diffusing panel-receiving frame structures(s) at the outer sign surfaces  102 . It will be further understood from a consideration of the noted figures that legend-bearing screens or signs  82  and  83  as well as prismatic panels  14  are preferably positioned on opposing respective sides of each sign structure  81  and are preferably in centered relation to central opening  88 . Light panel  13  is preferably mounted in central openings  88  in sandwiched relation between sign structures  81  as framed by the cooperative light panel-receiving frame structure(s).  
      Each sign structure  81  may thus be said to comprise light panel-receiving frame structure or light panel-receiving means as will be seen from a general inspection of  FIG. 27  at referenced numeral  89 . Diffused or prismatic panels  14  are preferably mounted in each sign structure  81  in central alignment on opposing respective sides of sign structures  81  outwardly adjacent to legend-bearing signs  82  and  83  at the diffused panel-receiving frame structure(s) as referenced at  100 . Diffused or prismatic panels  14  are fixedly received by diffused panel-receiving frame structure(s) and thus place hold legend-bearing screens or signs  82  and  83 . Optionally, the outer surface  102  of each sign structure  81  may comprise prismatic reflective sheeting  99  adjacent to the outer sign perimeter  103  as referenced in  FIGS. 24-26 , and  28  (note: only a fragmentary perimeter  103  is shown in  FIG. 28 ).  
      It will be further seen from an inspection of  FIGS. 24-28  that each sign structure  81  comprises a handle-receiving structure  90  or handle-sandwiching means adjacent a bottom or inferior end of each sign structure  81 . Handle-receiving structures  90  are integrally formed with the respective sign structure  81  in inferior adjacency to the respective central opening  88 . Handle-receiving structures  90  are sized and shaped to receive the superior terminal portion of handle assembly  16  such that the superior terminal portion of handle assembly is sandwiched between sign structures  81 . Certain fastening means or means for connecting handle assembly  16  to sign structures  81 , such as nuts and bolts, function to fasten handle assembly  16  to sign structures  81  as generally depicted in  FIG. 27  at  91 . It will be seen from a further inspection of  FIGS. 26 and 28  that certain fastener-receiving structures, such as bore apertures  92 , are formed in each sign structure  81  for receiving the fastening means. Similarly, it will be further seen from an inspection of  FIGS. 25 and 27  that certain fastening means function to connect display guards  84  to sign structures  81  In this regard, it is contemplated that nuts and bolts  91  function to fasten each display guard  84  to a respective sign structure  81 . It is contemplated that display guards  84  may function to protect prismatic panels  14 , legend-bearing signs  82  and  83 , light panel  13 , and certain superior areas of each sign structure  81  from damage, for example, if traffic control sign assembly  80  were dropped.  
      In the preferred alternative embodiment, batteries  15  are preferably mounted within battery pack  85  as housed within battery box  86  as generally depicted in  FIGS. 25, 29 , and  30 . It is contemplated that battery box  86  is attached in inferior adjacency to hand grip  6  so as to make the assembled traffic control sign assembly  80  less top heavy. Thus, it will be seen from an inspection of  FIGS. 25 and 30  that handle assembly  16  comprises electrical circuitry conduit  93  of a certain length to dispose battery box  86  in significant inferior adjacency thereto. Conduit  93  is further illustrated and referenced in  FIGS. 26-28 .  FIGS. 26 and 28  show conduit  93  in an optional abbreviated length and  FIG. 27  shows conduit  93  in a preferred elongate state. The inferior end of conduit  93  comprises means for connecting the same to battery box  86  as generally depicted in  FIG. 25  at exploded view connecting line  94 . Battery box  86  preferably comprises certain switch means  87  or selector switches; a low battery power alarm  95 ; a door  96  with latching handle  97  as referenced in  FIG. 25 ; and means for receiving telescopic handle  27  as further referenced in  FIGS. 25 and 30 . The reader will recall the foregoing descriptions of telescopic handle  27  for detailed specifications thereof.  
      A wire harness electrically communicates the power source (such as batteries  15 ) located in battery box  86  to light panel  13  via battery box  86  and conduit  93 . The wire harness is generally depicted in  FIG. 27  at  98 . The switch means, designed for turning batteries  15  “ON” in a holding or a flashing mode and for turning batteries  15  “OFF” have been generally referenced at  87  in  FIGS. 25 and 30 . A power source, such as batteries  15 , are located in battery box  86  as previously specified and are connected to two-sided bread board type LED light panel  13  for providing electrical power to light two-sided bread board type LED light panel  13 . It is contemplated that other power sources, such as solar power and external power, may be utilized to power certain electric circuitry contained in traffic control sign assembly  80 .  
       FIG. 29  generally and diagrammatically depicts certain electrical circuitry of the preferred alternative embodiment of the traffic control sign assembly. Light panel  13  is generally referenced as being in electrical communication with a drive circuit  104 , which circuit  104  is in electrical communication with both a power source (batteries  15  as collected in a battery pack  85  and as housed within battery box  86 ) and a control circuit  105 . Control circuit  105  preferably comprises certain microprocessor based timers and the like. In electrical communication with the control circuit  105  are certain inputs  106  as selectively activated by the user via the switch means as referenced at numeral  87 .  
      It is contemplated that traffic control sign assembly  80  may also provide means for converting and using power from a source such as the cigarette lighter of any vehicle (e.g. an emergency vehicle) using a standard power inverter or from an external battery pack, which pack may be included in a traffic control sign assembly kit, as previously described. In addition, the battery-powered power source can include battery packs (i.e. venus type) or the battery pack  85  can also be recharged whether by direct plug-in cord adaptor with standard voltage ratings or by removal of the battery pack from traffic control sign assembly  80  and placement on a standard charger.  
      It should be noted (by way of example) that the traffic control sign assembly  80  may be plugged into any of the following external power sources: any vehicular cigarette lighter (12V direct current) by utilizing a power converter assembly (provided separately or provided with the traffic control sign assembly kit); any vehicle with a generator (e.g. emergency vehicles) supplying alternate current by utilizing a power inverter assembly (provided separately or provided with the traffic control sign assembly kit); or a standard external battery pack for longer life of LED lights  22 .  
      Similar to the preferred embodiment, the preferred alternative embodiment comprises legend-bearing screen or sign  82  (preferably a L EXAN  type sign sheet) bearing the legend “STOP”, which legend appears directly behind or adjacent one of diffused or prismatic panels  14  and legend-bearing screen or sign  83  (preferably a L EXAN  type sign sheet) bears the legend “STOP” or “SLOW”, which legend appears behind or adjacent to another of diffused or prismatic panels  14  mounted to sign structure  81 . Lexan type sign materials are typically available in clear and opal versions and available on request in large quantities and in any colour and length. There is also a double-sided ultraviolet (UV) protected Lexan sheet for sign applications. This opal coloured (25% light transmission) Lexan version is given a UV coating on both sides during the production process.  
      Thus, traffic control sign assembly  80  preferably comprises sign structures  81  having central openings  88  that are defined by certain framework or frame structures. Sign structures  81  can be octagon shaped (as generally depicted in  FIGS. 24-26 , and  28 ), such as for a standard stop sign, as has been generally illustrated in the noted figures for ease of illustration, or sign structures  81  can be shaped as deemed necessary, it being noted that signs take on various shapes and sizes. In addition, sign structures  81  may also be painted with reflective paint or have reflective tape, such as glass bead type reflective tape, attached to its surface and edges to enhance the display of the message. Alternatively, as earlier stated, each sign structure may comprise prismatic reflective sheeting  99  to achieve a similar purpose. For example, a red color can be used for a “STOP” message and orange for “SLOW” and these colors can be painted to conform with standard shapes as used in traffic laws, such as octagonal for stop and triangular for yield and so forth.  
      It is contemplated that traffic control sign assembly  80  is constructed from these and other parts and is designed so as to be light-weight and the traffic control sign assembly  80  itself is intended to weigh approximately 5 pounds or less including batteries  15  and the like so that it may be easily held or supported by a person.  
      It will be recalled that  FIG. 20 ( a ) depicts a rendering of a “STOP-STOP” advisory;  FIG. 20 ( b ) depicts a rendering of a “STOP-SLOW” advisory; and  FIG. 20 ( c ) depicts a rendering of a “SLOW-SLOW” advisory, all of which advisories represent common or typical advisories. It will be seen from a comparative inspection of  FIGS. 26 and 28  that legend-bearing sign  82  may comprise a “STOP” type advisory and legend-bearing sign  83  may comprise a “SLOW” type advisory. It is contemplated that other advisories may easily be rendered upon the sign with appropriate adjustments.  
      It will be seen from an inspection of  FIG. 25  that diffused or prismatic panels  14  and legend-bearing signs  82  and  83  are preferably mounted in the respective sign structure  81  such that diffusing panel receiving means or a sign/panel-receiving structure  100  receives the same. Prismatic panels and legend-bearing signs  82  and  83  are thus received in central alignment on opposite sides of each central opening  88 . It will be recalled that diffused or prismatic panels  14  are preferably prismatic, meaning that they spread or diffuse light energy. Diffused or prismatic panels  14  thus preferably provide a cover for one side of the respective legend-bearing sign and two-sided bread board type LED light panel  13 .  
      Thus, it will be noted that in the preferred alternative embodiment, legend-bearing sign  82  bears the legend “STOP” and is located on the back of one of diffused or prismatic panels  14 ; further, legend-bearing sign  83  bears the either the legend “STOP” or the legend “SLOW” and is located on the back of the other of diffused or prismatic panels  14 . These legends are then aligned with LED lights  22  so that the spread of the light thereby increases the brightness and clarity of the message. The alignment and usage of the diffused (prismatic) panels  14  increases the distance from which the message can be read over ¼ mile from traffic control sign assembly  80  and the angle of view of light panel  13  so that the message can be read from up to a 170 degree line of sight from the center of sign structures  81 . In other words, given prismatic light-diffusing panels, viewers  108  may effectively view a traffic control message as indicated or depicted with a light ray  105  in  FIG. 31  at a distance of at least ¼ mile away from the light-emitting surface  106  of traffic control sign assembly  80  without obstructions intermediate the sign assembly  80  and the viewer  108 .  
      From an inspection of  FIG. 31 , it will be understood that the diagrammatic figures is not to scale and exaggerated for effect. Thus, the radius  110  of the sectioned circle depicted at  109  in  FIG. 31  should be read to have a measured magnitude of ¼ mile (1,320 feet). Further, viewers  108  may view the message  105  emanating from light panel  13  and diffused at the light-emitting surface  106  up to 85 rotational degrees (as depicted at  111 ) on either side of a light diffusion axis  107  (assuming a horizontal viewing plane) extending perpendicular through the center of the traffic control sign assembly  80  or vehicle signal light assembly  80 . A circle with radius of 1,320 feet will occupy approximately 5.47 million square feet. The section of circle depicted at  109  will thus occupy approximately 2.58 million square feet and thus the viewing range for traffic control sign assembly  80  (and  10 ) is at least on the order of 2.5 million square feet.  
      The ability to read the message from practically any orientation of traffic control sign assembly  80  dramatically increases the effectiveness of traffic control sign assembly  80  and practically overcomes any error in orientation of traffic control sign assembly  80  in the field, such as when the holder has accidentally turned planar portions of traffic control sign assembly  80  somewhat away from oncoming traffic. As discussed above, the messages on both sides of traffic control sign assembly  80  can then be read and understood at nearly all angles and from a large distance, thus improving protection of both the reader and the holder and people at the site at issue. Diffused or prismatic panels  14  are preferably constructed from phenolic type material (i.e. a type of reflective sheet covering) including pyramid type cones (i.e. dimpled) upon a surface thereof to deflect the light in all directions and to spread the light to enhance and equalize the brightness within the “pixel-looking” circles.  
      An additional significant feature of the present invention, as generally referenced in  FIGS. 9-12 ,  15 , and  15 ( a ), is handle assembly  16 . Handle assembly  16  is preferably secured to sign  11  for enabling traffic control sign assembly  80  to be hand held by a person, in a preferred embodiment. Handle assembly  16  preferably includes different embodiments including a telescoping handle  27  as illustrated and referenced in FIGS.  15 ,  15 ( a ),  25 , and  30 . Handle  27  preferably comprises screw means for screwed-in attachment and detachment means, a collapsible tripod embodiment for hands-free use, a modular or multi-sectioned handle that has screw attachment means, and a weighted base self-supporting stanchion embodiment that rests upon the ground. Handle assembly  16  may further preferably comprise a slide-on grip  28  as illustrated and referenced in  FIGS. 9, 10 ,  11 ,  15 , and  15 ( a ) and telescoping handle  27  can extend traffic control sign assembly  10  to over 6 feet high for better message visibility. Handle assembly  16  may preferably be constructed from wood, plastic, or metal materials, and may be slotted so as to be received and yoked or interlocked with the sign. It should be noted that handle assembly  16  should be of sufficient weight so that traffic control sign assembly  80 , in total, weigh approximately 5 pounds or less. Although not shown, other usages contemplated for the sign can include attachment to vehicles, such as school buses.  
      Further, it is contemplated that a hands-free, stand-mounted traffic control sign assembly  50  (as may be seen from an inspection of  FIG. 21 ) may enable the user to temporarily situate the sign assembly so that the user may be free to perform other activities (other than holding sign assembly  80 ). From an inspection of  FIG. 21 , it will be seen that stand-mounted traffic control sign assembly  50  preferably comprises a threaded sleeve  51 ; a locking knob  52 ; a tripod or four-legged stand  53 ; and a telescoping pole  54 . Threaded sleeve  51  threads up onto base of the handle. The tripod or four-legged stand  53  may preferably comprise foldable legs  55  for portability. Telescoping pole  54  is designed for height adjustment as does locking knob  52 . Note that the same telescoping pole may be utilized for the hand-held traffic control sign assembly or the stand-mounted traffic control sign assembly. With regard to the hand-held version, it is contemplated that a grip  6  (as referenced in  FIGS. 1 and 22 ) may be utilized in combination with handle assembly  16  to provide the holder with more comfortable structure with which to grasp and hold traffic control sign assembly  10 .  
      In construction and in use the present invention therefore provides traffic control sign assembly  80  that provides enhanced visual clarity, brightness, and coverage including distances of at least ¼ mile and at nearly any angle from which traffic control sign assembly  80  can be turned. Traffic control sign assembly  80  is highly visible, distinctly displays the appropriate warning messages, is capable of quickly being powered by various means, and is sturdy, lightweight, adaptable to different sites and under different working conditions, and is easy to use and manufacture.  
      While the above description contains much specificity, this specificity should not be construed as limitations on the scope of the invention, but rather as an exemplification of the invention. For example, it is believed that the spirit of the present invention teaches a traffic control sign assembly, which assembly essentially comprises first and second opposing sign structures, at least one bread board type LED light panel, first and second light-diffusing panels, batteries, attachment means, first and second legend-bearing screens, switch means, and a handle assembly. The sign structures each comprise an outer sign surface, light panel-receiving means, diffusing panel-receiving means, handle-sandwiching means, and an outer sign perimeter. The light panel is preferably positioned intermediate the sign structures in centered relation to the outer sign perimeters, the light panel being received by the light panel-receiving means. The light-diffusing panels are received by the diffusing panel-receiving means in central alignment on opposite sides of the light panel, the legend-bearing screens being sandwiched intermediate the diffusing panel-receiving means at the outer sign surface and the light-diffusing panels. The batteries are mounted in inferior adjacency to the light panel and in electrical communication with the light panel for providing electrical power for the light panel. This arrangement helps offset the weight of the upper sign assembly so that the resulting assembly is not as top heavy. The attachment means function to connect the sign structures to each other in unitary assembly.  
      The first legend-bearing screen with legend “STOP” is cooperatively associated with the first light-diffusing panel as received in the first sign structure and the second legend-bearing sign with legend “STOP” or “SLOW” is cooperatively associated with the second light-diffusing panel as received in the second sign structure. In other words, the first legend-bearing screen bears a first traffic legend adjacent the first light-diffusing panel and the second legend-bearing screen bears a select traffic legend adjacent the second light-diffusing panel, the select traffic legend being selected from the group consisting of the first traffic legend and a second traffic legend.  
      The switch means enable the batteries to power the light panel. The handle assembly is sandwiched intermediate the handle-sandwiching means, and thus, is secured to the sign structures for enabling the vehicle signal light assembly to be hand held by a person. The light panel means are thus cooperatively associated with the sign structures for providing light and for directing the provided light away from the plane in which the sign substantially lies. The light diffusion means are also cooperatively associated with the sign structures, which means are designed to diffuse the provided light away from and substantially parallel (up to about 85 rotational degrees on either side of an axis extending perpendicularly through the center of the sign). The power source is in electrical communication with the light panel means for electrically powering the light panel means. It is further contemplated that the traffic control sign assembly may comprise sign display means (such as the handle assembly) for otherwise supporting the sign, the supported sign for displaying visual messages to approaching viewers or passersby.  
      Essentially, a traffic control sign assembly is taught comprising opposing sign structures, light panel means, light diffusion means, connecting means, and a power source. Each opposing sign structure comprises an outer sign surface and an outer sign perimeter, the outer sign surface adjacent the outer sign perimeters being substantially planar. The light panel means are cooperatively associated with the sign structures centrally located relative to the outer sign perimeters. The outer sign perimeters are concentric about a light diffusion axis. The light panel means provide light, which is directed away from the sign structures.  
      The light diffusion means are cooperatively associated with the sign structures and the light panel means diffusing the light substantially parallel to the outer sign surface adjacent the outer sign perimeters. In this regard, it is contemplated that the light-diffusing means enable viewing of the illuminated visual messages up to 85 rotational degrees from the light diffusion axis. The connecting means connect the sign structures, the light panel means, and light diffusion means to each other in unitary assembly. Finally, the power source is in electrical communication with the light panel means for selectively electrically powering the light panel means.  
      Optionally, the traffic control assembly may comprise legend-bearing means, which are received intermediate the light panel means and the light diffusion means. The legend-bearing means enable display of legend-reinforced, illuminated visual messages to approaching viewers. The traffic control sign assembly may further comprise sign display means for supporting the sign structures, the supported sign structures for displaying elevated illuminated visual messages to approaching viewers.
