     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved illuminated roller skate wheel embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the illuminated roller skate wheel 10 of the instant invention essentially comprises the wheel structure 11 having a wheel conical cavity 12 to receive an illumination insert housing 13. The insert housing 13 is symmetrically oriented about a housing axis 13a (see FIG. 4). The housing includes an insert base plate 14 spaced from and parallel a transparent forward plate 16. The transparent plate 16 may be formed of translucent material and may be of various colorations. A socket 15 is directed into the base plate 14 directed towards the forward plate 16 symmetrically oriented about the axis 13a, as indicated in FIG. 4, for reception of the wheels axle and securement fastener. Such axle and securement fastener structure is typical of roller skate wheel construction and as exemplified in U.S. Pat. No. 4,648,610 incorporated herein by reference. 
     The insert housing is further formed with a conical side wall 17 for complementary reception within the wheel conical cavity 12. Further, the conical side wall 17 is arranged to include an adhesive layer 28 (see FIG. 5) for fastening of the housing within the wheel structure. A battery housing 18 is mounted within the housing in adjacency to the forward plate 16 along the axis 13a. A plurality of illumination bulbs 20 are diametrically aligned relative to one another and mounted within the housing symmetrically spaced from the axis 13a. The battery housing 18 includes a battery 19 therewithin, with a plurality of L-shaped electrical contact support legs 22 extending in electrical communication to the battery, each having a weighted electrical contact 23 at a free distal end of each contact leg spaced from the battery housing and battery 18 and 19 respectively. Each of the illumination bulbs 20 is mounted within an electrical bulb socket 24, with each bulb socket 24 having a rigid electrical contact leg 25 extending therefrom. Upon rotation of the roller skate wheel 11, the weighted electrical contacts 23 project for electrical communication with the rigid electrical contact legs 25 to complete electrical circuitry from the battery through the bulbs 20 for illumination of the bulbs. To this end, the L-shaped contact legs are of a resilient shape retentive material, wherein each of the weighted electrical contacts 23 is spaced from an associated contact leg 25 but upon rotation of the wheel 11, the electrical contact 23 extends radially from the battery housing and battery for electrical communication with the rigid contact leg 25. 
     The FIGS. 6 and 7 indicate the use of a concave forward plate 27 and a prismatic forward plate 26 respectively for alternative use relative to the forward plate 16. Further, the forward plates 16 or 26, 27 may be removable relative to the housing for maintenance of the battery 19 or may alternatively be sealed within the housing. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
