     FIG. 2 is a sectional view of the illumination device and the axle of the wheel depicted in FIG. 1 in magnified configuration. 
     For a better understanding of the invention reference is made to the following detailed description of the preferred embodiments thereof which should be taken in conjunction with the prior described drawings. 
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Various aspects of the present invention will evolve from the following detailed description of the preferred embodiments thereof which should be taken in conjunction with the prior delineated drawings. 
     The invention as a whole is depicted in the drawings by reference character 10. The illumination device 10 is intended for use in conjunction with a vehicle wheel 12, including tire 14, plurality of spokes 16, and axle 18. Axle 18 revolves around axis 20. Stem and bar 22 represents the remainder of a bicycle, which is of conventional configuration and not fully depicted in FIG. 1. Wheel 12 rotates according to directional arrow 24 in the normal manner. 
     Turning to FIG. 2, it may be observed that illumination device 10 is shown in section for the sake of clarity. Illumination device 10 includes a first container 26 having a wall portion 28 forming an inner chamber 30. Inner chamber 30 is capable of containing or holding a battery 32, which is commercially available. In addition, first container 26 possesses an aperture 32. Aperture 32 extends into a channel 34 having an opening 36 which is smaller than aperture 32 as shown in FIG. 2. Channel 34 overlaps wall portion 28 of first container 26. Such contact may be frictional, threaded, and the like. In any case, channel 34 is removable from first container 26 to gain access to battery 32. In addition, a lamp and socket 38 is at least partially located in first container 26. Lamp also includes a reflector 40 which electrically conductive material such as metal. Alternatively, first container 26 may be constructed of non conductive material such as plastic, wood, paper, and the like and include electrically conductive strips, lines, and the like, to permit electrical connection between conductive reflector 40 and bridging electrical wire 42. 
     Second container 44 is also depicted in the drawings and possesses a wall portion 46 forming an inner chamber 48. Inner chamber 48 holds another battery 50. Removable cap permits access to battery 50 and also serves to aid in the electrical connection between battery 50 and conductive wall portion 46 of second container 44. Again, second container 44 may be formed of the same material as first container 26, hereinabove described. In any case, conductive spring 54 electrically connects second battery 50 to cap 52 and connected wall 46. L-shaped conductor 54 electrically links battery 32 to battery 50 within first and second containers and 44. It should be noted that second container 44 includes an aperture 56 permitting communication between inner chamber 48 of second container 44 and inner chamber 30 of first container 26. Of course, first and second containers 26 and 48 may be formed integrally or separately. As depicted in the drawings, first and second chambers 26 and 44 constitute one piece. 
     Mounting means 58 is also found in the present invention for holding first and second containers at least partially around axle 18. For example, mounting means 58 may take the form of simply wedging device 10 within plurality of spokes 16. In addition, a strap 60 or a multiplicity of straps (not shown) may be used to hold device 10 to axle 18. Other mounting means such as screws, adhesives, magnets, and the like may be employed in this regard. It may be observed that device 10 contacts axle 18 in two places 62 and 64, which are separated radially about the outer surface 66 of axle 18. Thus, mounting means 58 at least partially holds illumination device 10 around axle 18 of wheel 12. 
     Means 68 is also provided for forming an electrical circuit between lamp and socket 38, battery 32, and battery 50. As prior described, lamp 38 electrically connects to conductive reflector 40, which is connected to electrically conductive wall 28 through wire 42. Electrically conductive spring 54 contacts cap 52, electrically connected to wall 46 of second container 44. Finally, L-shaped conductor 54 electrically interconnects batteries 32 and 50 to form a circuit. Although not depicted in the drawings, wire 42 may be interrupted with a switch to turn illumination device on and off as desired. Of course, alternate means may provide this function such as moving lamp and socket 38 inwardly and outwardly with the movement of channel 34 and the like. 
     In operation, illumination device 10 is loaded with batteries 32 and 50 and fastened to axle 18 of wheel 12 by mounting means 58. Means 68 forming the circuit is activated and permits the projection of light, indicated by multiplicity of ray lines 70, outwardly through opening 36 of channel 34. Such ray lines, further depicted in FIG. 1, indicate that light is reflected off tire rim 72 in various directions in the plane of wheel 12, as well as outwardly therefrom. The net effect is that the user of the vehicle associated with wheel 12 is easily seen at night through the rotation of wheel 12 and the reflection of the light rays 70 from illumination device 10 along rim 72 and outwardly therefrom. 
     While in the foregoing, embodiments of the present invention have been set forth in considerable detail for the purposes of making a complete disclosure of the invention, it may be apparent to those of skill in the art that numerous changes may be made in such detail without departing from the spirit and principles of the invention.
