BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The field of invention relates to bicycle brake lights, and more particularly pertains to a new and improved bicycle brake light wherein the brake light system is actuated upon braking of the associated bicycle. 
     2. Description of the Prior Art 
     The use of bicycle brake lights in association with brake calipers is well known in the prior art. Heretofore, the adjustment of the switching arrangement relative to the brake light has been of a relatively complex arrangement, as opposed to the instant invention which enables fine adjustment of the switching member. Further, the prior art brake lights have been of conventional configuration as incorporated by the instant invention, but wherein the instant invention proceeds to provide an aerial brake light for enhanced visibility. For example, U.S. Pat. No. 3,878,387 to Kovacic sets forth a brake light system wherein the switching member is mounted relative to a caliper arm or lever to complete the circuit, as opposed to the instant invention positioning the brake light upon a stable portion of the caliper on an opposite side of the caliper pivot axle. 
     U.S. Pat. No. 3,906,443 to Musselman sets forth a brake light circuitry wherein the switching member is actuated by contacts positioned through the brake shoe pad holder assembly. This arrangement encourages rapid wear of such contacts in its association with a bicycle wheel rim. 
     U.S. Pat. No. 4,031,343 to Sopko sets forth a bicycle brake light wherein the switch is provided and arranged on the caliper arms remote from the brake pads, but fails to provide the adjustability and stability of the instant invention as the switch is pivoted in its entirety with the cable, as opposed to the instant invention where the cable reciprocates through the switch. 
     U.S. Pat. No. 4,586,021 to Nickols sets forth a brake light wherein the switching member for the brake light is located between an arm of the caliper brake mechanism and the rear wheel yoke in a configuration remote from that of the instant invention. 
     As such, it may be appreciated that there is a continuing need for a new and improved bicycle brake light wherein the same addresses both the problems of ease of adjustment and effectiveness in use, and in this respect, the present invention substantially fulfills this need. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of bicycle brake lights now present in the prior art, the present invention provides a bicycle brake light wherein the same utilizes a switch fixedly mounted between opposed fixed arms of a single lever arm of the bicycle caliper in cooperation with the relatively movable arm and further provides for ease of adjustment of the switch mechanism to accommodate brake pad wear. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved bicycle brake light which has all the advantages of the prior art bicycle brake lights and none of the disadvantages. 
     To attain this, the present invention comprises a bicycle brake light wherein the same utilizes a switch member mounted between spaced arms of a first lever of a bicycle brake caliper mechanism in cooperation with the other relatively movable arm. The switch member accommodates the brake cable to be reciprocated therethrough with an internal adjustment cam to adjust a second contact relative to a first movable contact secured to the brake cable. A rear brake light may be mounted to the bicycle frame mechanism and used alone or in combination with an antennae light formed of a flexible, polymeric material with a transparent housing secured at its uppermost end with a light mechanism therein electrically associated with the switching mechanism and a self-contained battery. 
     My invention resides not in any one of these features per se, but rather in the particular combination of all of them herein disclosed and claimed and it is distinguished from the prior art in this particular combination of all of its structures for the functions specified.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved bicycle brake light embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the bicycle brake light apparatus 10 of the instant invention essentially comprises a combination with a conventional bicycle 11 formed with a forward wheel and a rear wheel 12 with a brake caliper 13 mounted in operative engagement with the rear wheel. Reference to FIG. 2 illustrates the caliper 13 with a first caliper arm 14 pivotally mounted about a central caliper pivot to a second caliper arm 15. The second caliper arm 15 includes a &#34;U&#34; shaped leg remote from the bracket pad arrangement on an opposite side of the caliper pivot. The &#34;U&#34; shaped leg 16 includes an upper and lower leg 16a and 16b  respectively spaced a fixed and parallel distance apart relative to one another. A switch 17 is mounted between the upper and lower legs 16a and 16b and receives the brake cable 18 reciprocatably therethrough with the brake cable fixedly mounted relative to the upper leg 16a via a cable guide 19 to direct the cable 18 therethrough. 
     Switch 17 includes a first reciprocating contact 20 fixedly secured to the cable 18 with diametrically opposed arcuate recesses 20a formed within the perimeter surface of the reciprocating cylindrical first contact 20 to receive guide ribs 22 that are electrically conductive and are mounted parallel to one another onto interior diametrically opposed surfaces of the cylindrical housing of the switch 17. A second contact 21 is adjustably mounted relative to an upper end of the switch housing with a single or plurality of return springs 23 to bias the second contact away from the first contact 22. The second contact slidably receives the brake cable therethrough. An elongate adjustment cam 24 is mounted rotatably above the second contact 21 and is rotated with a screw angle 25 formed with a forwardly positioned drive head that may include a screw driver fitting or a hexagonal recess to enable rotation of the screw axle 25. The axle 25 is fixedly secured to the adjustment cam 24 and is formed with a threaded rear terminal end portion 26 that is threaded through a rear wall of the housing of the switch 17 to enable rotation of the adjustment cam 24 by rotation of the forwardly mounted head that is accessible through a coaxially aligned opening through a cylindrical wall of the switch 17. The second contact 21 includes diametrically opposed arcuate second contact recesses 21a that are formed with an insulative layer to prevent electrical contact between the second switch 21 and the electrically conductive guide ribs 22. A first conductive wire 27 is in electrical communication with at least one guide rib 22 with a second conductive wire 28 in electrical communication with a second contact 21. Upon physical contact of the two electrical contacts 21 and 22, a circuit is effected through an associated battery 29 of a conventional dry cell configuration positioned as desired within the bicycle framework and thereby actuate lights 30 formed within the circuit. A first light 31 is formed with a forward transparent lens and a rearwardly positioned securement bracket for securement to a rear portion of the bicycle 11, as illustrated in FIG. 1 for example. FIG. 8 is illustrative of a second brake light that is optionally employed by the instant invention and utilizes a mounting bracket 34 to support an upwardly extending cylindrical resilient tubular rod 32 formed with a transparent lens cap 33 at its upper terminal end with associated electrical wires 27 and 28 directed coaxially of the resilient tubular rod 32. An included illumination bulb is actuated upon completion of the electrical circuit, as noted above. The resilient character of the tubular rod 32 accommodates impact with the light during conventional use of the bicycle. 
     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.
