   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to traffic lights and more specifically it relates to a traffic signal system for utilizing an efficient and simplistic structure to regulate vehicle and pedestrian traffic. 
   2. Description of the Related Art 
   Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field. 
   Traffic lights have been in use for years. Typically, traffic lights are used as signaling devices and are positioned at places, such as but not limited to road intersections and pedestrian crossings to indicate whether it is safe to proceed. 
   Traffic lights are generally comprised of a container holding a plurality of lights. When replacing or performing maintenance on the traffic lights it is generally required to hingedbly open and close the container to gain access to the traffic light. There is generally a wide array of movable parts and wiring associated with the container of the traffic lights, which makes performing maintenance on traffic lights tedious and cumbersome. 
   Traffic lights are also generally positioned at a high vertical height with a minimal amount of support structures nearby. Because of the lack of support structures, it is generally preferred to spend a minimal amount of time maintaining traffic lights. Traffic lights that include a wide array of parts and complicated container structures generally take longer to perform maintenance on because of the difficulty in accessing the traffic light. 
   While these devices may be suitable for the particular purpose to which they address, they are not as suitable for utilizing an efficient and simplistic structure to regulate vehicle and pedestrian traffic. Traffic lights with complicated container structures can prove to be tedious in performing maintenance on and also generally have an unnecessarily large amount of parts that are subjectable to being lost over time. 
   In these respects, the traffic signal system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of utilizing an efficient and simplistic structure to regulate vehicle and pedestrian traffic. 
   BRIEF SUMMARY OF THE INVENTION 
   In view of the foregoing disadvantages inherent in the known types of traffic lights now present in the prior art, the present invention provides a new traffic signal system construction wherein the same can be utilized for utilizing an efficient and simplistic structure to regulate vehicle and pedestrian traffic. 
   The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new traffic signal system that has many of the advantages of the traffic lights mentioned heretofore and many novel features that result in a new traffic signal system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art traffic lights, either alone or in any combination thereof. 
   To attain this, the present invention generally comprises a support member including at least one receiver member and at least one light module including a plug member extending outwardly from the light module, wherein the plug member is positionable within a cavity of the receiver member.

The horizontal portion of the second tab  48  is initially positioned along an outer edge of the receiving portion  58 , wherein when the light module  50  is rotated the horizontal portion of the second tab  48  is positioned within the locking portion  59  to prevent the light module  50  from rotating further as illustrated in  FIGS. 5 and 6 . 
   Further, an outer lip of the second tab  48  is preferably initially positioned within the receiving portion  58  of the second slot  57 , wherein when the light module  50  is rotated the lip of the second tab  48  is repositioned over the locking portion  59  to prevent the light module  50  from moving horizontally outward as illustrated in  FIGS. 5 and 6 . The second tab  48  preferably locks within the locking portion  59  of the second slot  57  at a simultaneous time as the plug members  52  lock into the receiver member  24  when rotating the light module  50 . 
   The second tab  48  is released from the locking portion  59  and forced into the receiving portion  58  by pushing a dividing member between the receiving portion  58  and the locking portion  59  perpendicularly away from the receiving portion  58  and locking portion  59 . When the second tab  48  is positioned within the receiving portion  58  the light module  50  is preferably able to be removed from the housing unit  40  and the support member  20 . 
   F. In Use 
   In use, the support member  20  is first mounted at an adequate position to serve as a traffic signal light. The support member  20  may be mounted via threadably mounting the first end and second end to a support structure. The support member  20  may also be mounted by being clamped against a pole or other structure. It is appreciated that the traffic signal system  10  may be mounted in a plurality of other manners consistent with mounting a traffic light. 
   After the traffic signal system  10  is securely mounted the electrical wiring  28  may be accessed via the container  29  and subsequently connected to an outside power source. The light modules  50  are now inserted within the openings  46  of the housing unit  40  so the second extending portion  53  of the plug members  52  enters the first extending portion  27  of the cavities  26  and the first tab  47  extends through the first slot  56  and the second tab  48  extends within the second slot  57 , referred to as the initial position. The light modules  50  are now rotated, thus securing the light modules  50  within the housing unit  40  and support member  20 . 
   When removing a light module  50  from the housing unit  40  and support member  20  the lens  54  is depressed firmly substantially near the slot  57  to disengage the second tab  48  and the light module  50  is pushed slightly inward to disengage the plug members  52 . The light module  50  is now rotated in an opposite direction as the light module  50  was rotated when the light module  50  was attached to the housing unit  40  and the support member  20 . Once the light module  50  reaches the initial position it may be removed by pulling the light module  50  perpendicularly outward from the opening  46  and the receiver member  24 . Another light module  50  may subsequently be replaced within the housing unit  40  and the support member  20 .
