Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to signaling apparatus and more particularly pertains to a new and improved signaling apparatus which may be magnetically securable to a wide range of vehicles particularly trailer-like vehicles for temporary use in over-the-road situations mandating the use of a signaling means. 
     2. Description of the Prior Art 
     The use of signaling devices is well known in the prior art. As can be appreciated, these devices have normally involved permanent wiring or different types to enable these devices to effectively functioning for their intended purpose. In this connection, there have been several attempts to develop signaling devices which may be readily and efficiently utilized. For example, U.S. Pat. No. 2,044,300 to Hans illustrates the use of a signaling device with particular message illustratable thereon and of conventional permanent wiring to the chassis of a motor vehicle. While a functional solution for a particular situation, the hard wiring of the passing indication apparatus performs a function that is not of universal applicability and furthermore the apparatus lack clarity due to the non-uniform message formed on the included lenses. 
     U.S. Pat. No. 2,854,650 to Baker is another in a series of hard wired signs to inform a following motor vehicle whether or not it be safe to pass said vehicle. Again, the hard wiring of the sign limits application to a single vehicle and furthermore is positionally configured to be somewhat difficult to understand due to relative size and complexity of the included message formed on the signaling apparatus itself. 
     U.S. Pat. No. 3,471,829 to Kahn discloses the use of sequential signaling device of again conventional hard wiring to a particular vehicle limiting use thereof to that particular vehicle. 
     U.S. Pat. No. 3,683,330 to Lancaster is a further example of a message display sign to be positioned centrally of a trailered vehicle to indicate to a following motorist whether it may or may not be safe to pass. As in other prior art, limited application due to the hard wiring and complex message positioned on the sign, results in a signaling device of limited application and of confusing message conveyance. 
     U.S. Pat. No. 4,495,553 to Haynes illustrates an arrow indication device of again hard wired nature for use with a motorcycle indicating a desired turn maneuver by a user thereof. Again the problem of providing an easily securable and adaptable turn signaling apparatus for use with a multitude of vehicles and particularly trailers has not been addressed. 
     As such it can be appreciated that there is a continued need for a new and improved turn signaling device which addresses both the problem of adaptability and ease of use and in this respect, the present invention substantially fulfills this need. 
     SUMMARY OF THE INVENTION

     BRIEF DESCRIPTION OF THE DRAWINGS 
     The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein: 
     FIG. 1 is an isometric view of the present invention as installed onto a typical trailer as utilized in commerce and particularly in agriculture. 
     FIG. 2 is a top orthographic illustration depicting the top operative surface of my remote control device and the configuration of the indicative surface of my individual turn signal modules. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIG. 2 thereof, a new and improved turn signal apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that turn signal apparatus includes a remote control device 11 of conventional construction including a battery containment compartment illustrated in phantom at 12 for powering the remote control device. A push-button for on/off control of the device is positioned centrally of the top forward face of the device with a button 14 to energize a right turn indicator module 14a and a left turn button 15 to energize a left turn module 15a, as illustrated in FIG. 2. Each module 14a and 15a each containing replaceable battery supplies (not shown) furnishing power for said modules. Respective right and left turn modules 14a and 15a are configured with forward surfaces 16 and 17 as mirror images of one another. Positioned along rearward facing surfaces of the respective modules are permanent magnets indicated at 18 and 19 respectively. Such magnets are of sufficient strength and force to enable secure and sure attachment to a preselected metal portion of a vehicle. Also positioned on forward faces 17 and 16 respectively are flashing red light structures 20 and 21 spaced above faces 17 by use of standards 22 and 23. The flashing of lights 20 and 21 is effected by actuation of either respective turn signal module. 
     Right turn module 14a and left turn module 15a have positioned in prominent illuminated orientation to indicate a right and left turn respectively, indicator arrows 24 and 25 for right and left turn module respectively. lndicator arrows 24 and 25 are formed of a yellow tinted glass in conjunction with yellow bulbs to indicate a glowing yellow light upon energization of a pre-selected right or left turn button by the control device. Accordingly when either module 14a or 15a is activated, a respective indicator arrow and flashing light act in concert. In contrast to the yellow turn arrows, the flashing lights 20 and 21 are red. The combination therefore of the red flashing lights 20 and 21 with the yellow or amber colored arrows 24 and 25 provide a clear unmistakable indication of turning intention by a user. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description and illustrations. However, a further discussion relative to the manner and usage of operation will be further provided. In use, one merely attaches by means of the magnetic securement elements 18 and 19 the right and left turn modules 14a and 15a upon a typical trailer apparatus 26. The user, while riding in a tractor-like device 27, will position the remote control device 11 conveniently to enable easy access thereto. When a right turn, for example, is desired the user will push button 14 thereby energizing module 14a whereupon amber turn arrow 24 will be illuminated as well as red flashing light 21 to act in concert with amber light 24. The combination of the red and amber in concert provides an unmistakable and clear indication of an imminent turning event to a following vehicle. 
     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.
