       FIELD OF THE INVENTION 
       [0005]    This invention relates to illuminating bicycle tires. 
       BACKGROUND OF THE INVENTION 
       [0006]    Bicycle wheels have been illuminated in a number of ways over the years, with devices such as lamps (See Betts, U.S. Pat. No. 540,605) and reflectors (See Rider, U.S. Pat. No. 2,293,849). More recently, it has become popular to use light emitting diodes attached to the wheels or spokes of the bicycle with an adhesive as shown in the background art below. However, there is presently no disclosed method for drilling holes into the wheel and inserting LED lights into the hole, perhaps because of concerns for wheel stability. The disclosed invention solves those problems. 
       BACKGROUND ART 
       [0007]    The Moore U.S. Pat. App. No. 2010/172145 teaches a mount for mounting a light to a bicycle where. It does not teach drilling holes into the wheel, nor does it explain how to determine the positions of the holes. 
         [0008]    The Washington U.S. Pat. No. 7,213,953 teaches an illumination device designed to be attached to a wheel with adhesive material. It teaches away from the drilling technique used in the current application by emphasizing a different and inadequate method of attachment. 
         [0009]    The Reim U.S. Pat. No. 7,079,042 teaches method for placing an illuminated display on a wheel. Like the Washington patent, it teaches away from drilling into the wheel by teaching an adhesive layer connecting the LED to the wheel. 
       BRIEF SUMMARY OF THE INVENTION 
       [0010]    Methods, systems, and other means are provided for a method for building side illumination for a wheel. In accordance with some embodiments the method for building side illumination for a wheel involves a user first conducts a feasibility study to collect data about stress points of the wheel. Second a user determines locations on the wheel for lighting devices based on analysis of the data collected. Next, a user forms a plurality of cavities in the wheel to accommodate the lighting devices. Finally, a user installs the lighting devices into the plurality of cavities. Additionally, reinforcement can be provided into the cavities as necessary. The cavities can be made by a variety of techniques including active drilling, horizontal drilling, cross drilling, vertical drilling, longitudinal drilling and a variety of other methods. These cavities can be threaded to hold the light better into the wheel.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0017]    Embodiments of the present invention overcome many of the obstacles associated with illuminating bicycle wheels, and now will be described more fully hereinafter with reference to the accompanying drawings that show some, but not all embodiments of the claimed inventions. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout. 
         [0018]      FIG. 1  shows method  10  for building side illumination for a bicycle wheel. Method  10  begins with Step S 11  which comprises conducting a stress concentration analysis. Methods for stress testing wheels are well known. See Fischer, U.S. Pat. No. 6,116,084 which teaches a device for testing a wheel. When wheels are stress tested they provide data for determining the mechanical properties of those wheels. Once those properties are known traditional techniques for determining stress concentration and how those stresses are affected by inserting cavities are well known as well. See Pilkey, et al., Peterson&#39;s Stress Concentration Factors (2008). The present invention, in Step S 11 , uses these well-known methods and others to determine the effect of making cavities in a wheel in different locations. Notably, wheels already have cavities based on spokes that are inside them, and the present invention merely determines where additional cavities would have the least effect on predictable loading in a wheel. In particular, the analysis may include performing an appropriate series of tests to collect sufficient data about displacement, reaction force, stress, and strain energy points of the bicycle wheel. The tests may be performed by field testing, software simulation or both depending on user preference. 
         [0019]    Step S 12  comprises determining locations on a wheel for lighting devices based on analysis of the data collected in Step S 11 . Analyzing the collected data can provide information about the safest points where the bicycle wheel may be penetrated to create a plurality of cavities to receive the lighting equipment. The location of a cavity can depend upon the structural integrity of each individual wheel design. 
         [0020]    Step S 13  may include forming the plurality of cavities in the wheel to accommodate lighting devices. Cavity forming may be done by removing material from the wheel or the cavity may be designed into the mold of the wheel prior to casting. For instance, this can be done by active drilling, horizontal drilling, cross drilling, vertical drilling, longitudinal drilling or a variety of other methods. 
         [0021]    After the plurality of cavities have been formed in Step S 13  they may be reinforced in Step S 14  which may include installing reinforcing elements to support the plurality of cavities formed in the wheel. The reinforcing element&#39;s material, shape, and size may vary upon the material, shape, and size of the wheel. Reinforcement is important to resolving the matter of structural integrity which has been untouched by the prior art. 
         [0022]    Step S 15  may include installing the lighting devices into their receptive cavities. As shown in  FIG. 5  below, this can be done by mechanically coupling switches, LEDs and batteries. 
         [0023]      FIG. 2  shows bicycle  40  using coupled with the method shown in  FIG. 1 . Bicycle  40  comprises wheel  12 . Wheel  12  is mechanically coupled to tire  14  as is well known in the art. Wheel  12  further comprises LED lights  16  as shown in more detail in  FIG. 3 . 
         [0024]      FIG. 3  shows wheel  12  in more detail. As explained above wheel  12  contains a plurality of LED lights  16  which are placed as determined in method Step S 11 , Step S 12 , Step S 13  and Step S 14  as explained in  FIG. 1 . LED lights  16  are inserted in wheel  12  as explained in method Step S 15  and shown in  FIG. 4  and  FIG. 5  below. 
         [0025]      FIG. 4  shows a section view of wheel  12 . As indicated above wheel  12  is mechanically coupled to tire  14 . Here, LED light  16  is electrically coupled to switch  18  which is further electrically coupled to batteries  20 . A user can activate switch  18  to turn LED light  16  on or off depending on user preference. A user can turn as many or as few LED lights  16  on or off as one chooses. This differs from the Reim patent above that requires a complicated computer program to turn lights on and off. 
         [0026]      FIG. 5  shows an assembly drawing of threaded cavity  22 . A first LED light  16  is mechanically coupled to a first switch  18  where the first switch  18  is threaded with a first thread. The first thread can be threaded into a second thread in threaded cavity  22  completing a first mechanical couple. In order to complete the electrical couple noted in  FIG. 4  above switch  18  will need to have a series of batteries  20  pressed against it. Further, a second LED light  16  is mechanically coupled to a second switch  18  where second switch  18  is threaded with a third thread. The third thread can be threaded into the second thread in threaded cavity  22  completing a second mechanical couple. As shown in  FIG. 1 , the technology of  FIG. 5  can be used to create a plurality of threaded cavities.
