     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved vehicular abutment alarm apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the vehicular abutment alarm apparatus 10 of the instant invention essentially comprises mounting to an associated vehicular trailer 11, having a trailer top wall 12 spaced from a trailer front wall 13. A vehicular cab 14 is provided, having an interior cab cavity, such as indicated in FIG. 8. 
     A first switch 15 is mounted in a spaced relationship relative to a vehicular front wall 13, wherein second and third switches 16 and 17 respectively are mounted at spaced intervals along the trailer top wall 12, A receiver unit 18 is mounted within the vehicular cab 14 in electrical communication with the first, second, and third switches 15, 16, and 17 respectively through an associated electrical communication cable 31. 
     The FIG. 2 indicates the receiver unit 18 having a housing top wall 25, wherein an on/off switch 26, as well as a speaker member 27 and illumination bulb 28, project in electrical communication with the batteries 29 and with the electrical communication cable 31. The first switch 15 is typical of the construction of the second and third switches as well and includes a switch housing having in connection with the first switch, first switch housing slots 30 for mounting to an associated mounting bracket 19, such as indicated in the FIGS. 1 and 5. The mounting bracket 19 includes a first wall 20 spaced from and parallel a third wall 22, having an interconnecting second wall 21 orthogonally oriented to the first and third walls 20 and 22, wherein the first wall 20 includes first wall slots 23, wherein the third wall includes third wall slots 24. The first wall slots 23 permit height adjustment mounting of the mounting bracket 19 to the vehicular front wall 13 to align the second wall 21 in adjacency to the top wall 12. A third wall 22 having the third wall slots 24 is arranged for mounting of the first switch housing slots 30 therealong utilizing conventional mechanical fasteners to position a projecting rigid rod 37 in a spaced relationship beyond and above the trailer top wall 12. The rigid rod 37 is in electrical communication with a first cable member 31a of the electrical communication cable 31 (see FIG. 4), wherein a second cable member 31b is in electrical communication with a metallic first contact 33 mounted to the housing top wall 22 of the first switch housing 30. The first contact 33 is provided with a concave top wall 34, wherein a metallic second contact 35 having a concave second contact bottom wall 36 is arranged in confronting relationship relative to the concave top wall 34, wherein the metallic second contact 35 is of a generally semi-spherical configuration having an annular contact edge 35b in spaced adjacency to the concave first contact top wall 34. In this manner, pivotal displacement of the rigid rod 37 relative to the first contact top wall 34 effects communication and completes electrical circuitry, wherein electrical communication to the batteries 29 effects simultaneous actuation of the illumination bulb 28 and an audible alarm operative through audible amplifier portion 27a. A polymeric spring 38 is interposed between the concave first contact top wall 34 and the concave second contact bottom wall 36. Further it should be noted that the first cable member 31a is in electrical insulative relationship relative to the metallic first contact 33 as it is directed therethrough and in turn is in electrical communication with the rigid rod 37. 
     The FIGS. 6-8 indicates the use of a remote alarm housing 39 arranged for electrical communication with the receiver unit 18 utilizing whatever conventional jack structure is available, such as indicated in FIG. 6, to electrically communicate the remote alarm housing 39 with the electrical communication cable 31. The remote alarm housing 39 includes a remote housing front wall 40 spaced from a remote housing rear wall 41, wherein the rear wall 41 includes a ferromagnetic plate 45 to permit magnetic adherence of the remote alarm housing 39 to an associated dashboard within the motor vehicle, as indicated in FIG. 8. A second speaker 42, as well as a second illumination bulb 43, are mounted to the housing front wall 40, wherein to the remote electrical communication cable 44, simultaneous audible alarm through the second speaker 42, as well as illumination of the second illumination bulb 43, is provided. The second speaker 42 and the second illumination 43 are arranged for direct current communication with the electrical communication cable 31 and are similarly powered by use of similar structure as indicated relative to the receiver unit 18. 
     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.
