Although elements may be described above as acting in certain combinations and even initially claimed as such, it is to be expressly understood that one or more elements from a claimed combination can in some cases be exercised from the combination and that the claimed combination can in some cases be excised from the combination and that the claimed combination may be directed to a subcombination or variation of a subcombination. 
         [0033]    Referring now to  FIG. 1 , which illustrates the traffic light assembly for a single light  100  having a housing  110 , a circular display screen  120 , a lid  130 , an optional camera  180 , and a signal transmitter  190 . In one preferred embodiment each single light is approximately 76 centimeters in diameter and the circular display screen is comprised of a platinum television screen although other various screens can be used such as LED, projection lamp, OLED, and LCD screens. A screen shield being comprised of transparent plastic and being 1 centimeter thick covering the entire light can also be used to protect the circular display screen  120  from damage. Each circular display screen  120  is surrounded by a square housing  110  being approximately 92 centimeters in diameter and 8 centimeters wide. In one preferred embodiment the housing  110  is comprised of tin and steel for stability and durability and is in the color black to make the color lights easier to distinguish and see. It is also contemplated that the traffic light contains one or more micro-processors which will allow it to perform certain processes and also send, receive and process transmitted signals. 
         [0034]    In  FIG. 2 , a typical three light traffic light assembly  200  is shown being comprised of a housing  210 , a circular display screen  220 , a lid  230 , an optional camera  280 , and a signal transmitter  290 . In another preferred embodiment, the three light traffic light assembly  200  can be configured in a horizontal fashion as opposed to a vertical fashion as shown in  FIG. 2 . 
         [0035]      FIG. 3  shows one preferred embodiment of the circular display screen for the green light comprised of a green spherical center G and a black solid band B in the shape of an outer ring. Even if the driver is visually impaired (e.g. color blind) or the green color of the light is hard to distinguish because of external influences, the ability of the driver to see the spherical center G and the black solid band B, he or she can still recognize that the light is green by the visual markings of the light.  FIG. 4  depicts the same green light with arrow displays  322  on the central display region  326  in the color of green G, which is surrounded by the circumferential display region  324  in the color black B. The arrow displays  322  are also in the color of black B and are approximately 60 centimeters in length from point to rear. The arrow display shaft is approximately 40 centimeters. From the point of the arrow to the arrow base is approximately 30 centimeters and the bases of the arrow are 10 centimeters each. 
         [0036]      FIG. 5  shows one preferred embodiment of the circular display screen for the yellow light  420  comprised of a yellow spherical center Y and a black B solid band  423  in the shape of an outer ring and a circumferential display region  424  which is comprised of black color sections  424 A and non-black color sections  424 B. For the yellow light, the non-black color sections are in the color yellow Y. In one preferred embodiment, the yellow light  420  is capable of blinking. When blinking, the central display region  426  would change from solid yellow Y to solid black B but the non-black color sections  424 B would remain. Even if the driver is visually impaired (e.g. color blind) or the yellow color of the light is hard to distinguish because of external influences, the ability of the driver to see the non-black color sections as dashed lines, he or she can still recognize that the light is yellow by the visual markings of the light. The non-color sections  424 B are approximately 10 centimeters from the central display region  426 . 
         [0037]      FIG. 6  shows another preferred embodiment of the yellow light  420  with corresponding arrow displays  422  in the color of yellow Y. As seen in  FIG. 6 , the directions of the arrow displays  422  may be shown in variety of fashions including the typical up, down, right and left directional cues. The arrow displays  422  are also in the color of black B. Again, drivers can always recognize the light is yellow by seeing the dashed non-black color sections  424 B, even if for instance that the driver is color blind. 
         [0038]      FIG. 7  provides another illustration of a preferred embodiment of a blinking yellow light  420  while containing an arrow display  422 . Even while blinking, drivers will recognize that the light is yellow by the dashed non-black color sections that pertains to only the yellow light. 
         [0039]      FIG. 8  shows one preferred embodiment of the circular display screen for the red light  520  comprised of a central display region  526  in the color of Red R and a solid black band  523  in the color black B, surrounded by a circumferential display region  524  in the color of red R. When blinking as shown in  FIG. 9 , the central display region  526  will switch from solid red R color to solid black B color, however the red R circumferential display region  523  will remain as a constant.  FIG. 10  shows another preferred embodiment of the red light  520  with corresponding arrow displays  522  in the color of red R. The arrow displays  522  may be shown in variety of fashions including the typical up, down, right and left directional cues. The arrow displays  522  are also in the color of black B. Even if the driver is visually impaired (e.g. color blind) or the red color of the light is hard to distinguish because of external influences, the ability of the driver to see the solid black B band  523  and the circumferential display region  524  as a solid unbroken ring, he or she can still recognize that the light is red by the visual markings of the light. 
         [0040]      FIG. 11  provides another illustration of a preferred embodiment of a blinking red light  520  while containing an arrow display  522 . In one preferred embodiment, for certain emergency circumstances, the red light  520  has the ability to depict a white flash W to attract more attention from drivers as shown in  FIG. 12 . The drivers will still understand that the light is Red through the circumferential display region  524  as a solid unbroken ring. 
         [0041]      FIG. 13  shows one preferred embodiment of circular display screen for a countdown traffic light that changes color  620  comprising of a numerical display  620 , a solid black B band  623 , a circumferential display region  624 , and a central display region  626 . This countdown traffic light provides added features to the traffic light assembly by being able to provide additional information to drivers. Aside from having a numerical display  620 , one can contemplate that the numerical display  620  may feature other information such as traffic congestion, accident warnings/notifications, amber alerts and a host of other highway and traffic related information. In order for the light to be able to perform and display a countdown or other informative displays, it is contemplated that the traffic assembly light contains a microprocessor to perform such processes. 
         [0042]    Turning to  FIG. 14 , one preferred embodiment of a full traffic light assembly is shown comprising of the red, yellow and green lights as described above. A typical scenario of a red-light stop transitioning to a green-light go is clearly depicted. 
         [0043]    Thus, specific embodiments and applications of the traffic light assembly subject matter contained in the present invention have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalent within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. The claims are thus to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted and also what essentially incorporates the essential idea of the invention. In addition, where the specification and claims refer to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
