BACKGROUND 
     1. Field of the Invention 
     This disclosure relates generally to an attachable, portable, illumination apparatus, and more particularly to embodiments for attaching lighting to creepers which are used by mechanics to gain access to the underbody of a vehicle. 
     2. Description of the Related Art 
     A well-known tool used by auto mechanics is a low-profile, wheeled platform, commonly known as a creeper, in which the mechanic may lie supine thereon, in order to look up at and gain better access to the underbody of a vehicle. 
     Auto mechanics and other tradesmen, technicians, and craftsmen have been seeking improved illumination solutions while using creepers. In addition to improved types of mechanics&#39; lights for illuminating the mechanics&#39; working area, the existence of other types of mechanics&#39; lights are sold as a single unit with the creeper, where the light is integrated into the design of the creeper. 
     As more and more improvements are made in general to lighting and luminescence, there is a need for such improvements to be energy-saving, sustainable, and applicable to industries that suffer from dimly lit work areas. Thus, an attachable and portable, lighting assembly, which is sold as an off-the-shelf, aftermarket, attachment for retrofitting to existing mechanics&#39; creepers in wide use within the auto mechanic industry, is one such solution.

     The present disclosure provides a rail lighting and lamp attachment  100  to be utilized with a vehicle maintenance platform or mechanic&#39;s creeper C. The attachment  100  is configured to be attachable to the railing of widely used creepers C. The light source  20  is configured to attach to the side rails of the creeper C. Wiring  30  electrically connects the attachment&#39;s  100  rails or railing  10  to one another, providing an electrical pathway  90  for operation. Light source  20  is powered by a rechargeable power source  50 , having an on/off switch  40 . Magnets  60  are disposed on the underside of the railing  10  to allow the railing  10  to slip-fit on the creeper&#39;s C side rails and head rail. 
     Referring to  FIG. 1 , an isometric view of an exemplar rail lighting and lamp attachment  100  for a vehicle maintenance platform C according to different embodiments of the present disclosure is shown. The railing sections  10  of the lighting attachment  100  are separable for portability and re-attachable for operation. The rails or railing  10  include a head rail  12 , left mounting rail  14 , and right mounting rail  16 . The three rails  12 ,  14 , and  16  each include a channel  13 ,  15 , and  17  on the underside (see  FIGS. 2-4 and 6  for channels  13 ,  15 , and  17 ) for coupling to the corresponding rail of the creeper C (see  FIG. 5  for use with creeper C). It should be understood persons of ordinary skill in the art that the rails  10  are constructed from any suitable material that is durable and formable in its shape to slip-fit over common, widely used creepers C and creeper railings. Such materials include, by way of example, aluminum, stainless steel, galvanized steel or blends thereof. 
     With continuing reference to  FIG. 1 , the light sources  20  (generally) can be disposed on the left mounting rail  14  and right mounting rail  16  in a serial manner. The light sources  20  are configured to target regions underneath the vehicle for illumination and arranged such that light emitted from the light sources  20  is projected towards the target region. In one embodiment of the present disclosure, the light sources  20  may be Light Emitting Diodes (LEDs) arranged as an LED array (left array  22  and right array  24 ) on each side of the attachment  100 . It should be apparent to persons of ordinary skill in the art that various other light sources besides LEDs may be utilized. 
     Now, with reference to  FIGS. 2-4 , end views of each of the rails  10  are shown. In  FIG. 2 , head rail  12  is shown with channel  13  and magnet  64  (to be described later) for attachment to a head rail portion of the creeper C. Next,  FIG. 3  shows the LED left array  22  of the left mounting rail  14 . Also illustrated are channel  15  and magnet  62  (to be described later) for attachment to a left side rail portion of the creeper C. Similarly, in  FIG. 4 , LED right array  24  of the right mounting rail  16 , as well as channel  17  and magnet  65  (to be described later) for attachment to a right side rail portion of the creeper C are shown. Tunnels  23  and  25  are openings provided on the underside of the LED arrays  22  and  24 , respectively, with particular reference to  FIGS. 3 and 4 . 
     In a non-limiting embodiment, with continuing reference to  FIG. 2  and now with reference to  FIG. 6 , wiring  30  of the rail lighting and lamp attachment  100  are described. Male connectors  32 ,  36  and corresponding female connectors  34 ,  38  of the wiring  30  are, by way of example, a type of male-female connector and wiring known as Deutsch connectors and Deutsch wiring from Deutsch Industrial Products Division. Any type of push-pull configuration connectors are contemplated by the present disclosure. During operation, the wiring  30  and connectors  32 ,  34 ,  36 ,  38  help complete the electrical pathway  90  (to be described later) when properly connected together and positioned on the creeper C (see  FIG. 5  for use with creeper C). On the other hand, the wiring  30  and connectors  32 ,  34 ,  36 ,  38  when disconnected separate each of the three rails  10  from one another for portability. Further, it is contemplated by the present discourse that the push-pull type connectors of the attachment  100  can be used to connect with a printed circuit board (PCB). The present disclosure, however, is not limited by the type or brand of connectors and wiring, so long as there are pins or lead wires or other contacts available for completion of the electrical pathway  90  and for connection with a PCB. 
     In another embodiment of the disclosure, power source  50  is coupled to the light source  20  (as depicted in  FIGS. 1, 5, 6, and 7 ). The power source  50  is coupled to the left array  22  and left mounting rail  14 , in a non-limiting embodiment. It should be apparent to persons of ordinary skill in the art that power source  50  can be coupled to any one of the rails  10 . 
     Examples of the power source  50  may include, but are not limited to, a rechargeable battery. The battery  50  can be nickel cadmium, nickel-metal hydride, lithium-ion, or the like. In one embodiment of the disclosure, the battery  50  may have a voltage of about 12 volts. However, it should be apparent to a person skilled in the art that batteries with different voltage may also be utilized as the power source  50 . Further, the power source  50  may be recharged to a desired voltage level when required. In addition, the power source  50  may be connected to an external power source such as a wall socket through a power supply port (not shown), for charging to the power source  50  to the desired voltage level. 
     Power source  50  is housed within battery box  52 . Battery box  52  can be formed as part of the rails  10  or attached with a threaded screw to any one of the rails  10 . It should be apparent to a person of ordinary skill in the art that the power source  50  may be coupled/housed/attached at various other positions of the attachment&#39;s general structure and design  100 . 
     In continuing reference to  FIGS. 1, 5, 6, and 7 , battery  50  is electrically connected to the light sources  20  through an internal wiring  30  and push-pull plug connectors  32  to  34  and  36  to  38 . In addition, attachment  100  includes an electrical switch  40  configured to activate/deactivate the light sources  20 . Specifically, when the electrical switch  40  is in an ‘ON’ state, the power source  50  and light sources  20  (and LED lamp  70 , to be described later) are electrically connected to the electrical pathway  90  (to be described later). Further, when the electrical switch  40  is in an ‘OFF’ state, the power source  50  and the light sources  20  (and LED lamp  70 ) are disconnected from the electrical pathway  90 . 
     In a non-limiting embodiment, the attachment  100  is capable of being attachable, detachable, and re-attachable to the creeper C. As illustrated in  FIGS. 1-4 and 6 , a known type of coupling mechanism may include one or more rare earth magnets  60 . Turning to  FIGS. 1 and 6  specifically, magnets  61 ,  62 ,  63 ,  64 ,  65 , and  66  are disposed in pairs on each rail&#39;s  10  channel-side. The present disclosure contemplates various other coupling mechanisms which may be utilized for coupling the attachment  100  to the creeper C, apart from utilizing magnets  60 . 
     Referring to reference numeral labels  70 ,  72 , and  74 , throughout the various drawings as illustrated, a gooseneck  72  type LED lamp  70  is positioned on head rail  12  to provide another more focused, repositionable light source  70 . The gooseneck  72  can be about 18 inches in length. Those of skill in the art will appreciate that any suitable lamp alternative is contemplated as being within the spirit and scope of the invention. 
     As disclosed above, the attachment  100  is configured to be detachably coupled to the creeper C. In particular, the rail lighting and lamp attachment  100  is detachably coupled to a conventional creeper C. Accordingly, in a non-limiting embodiment of the present disclosure, the left mounting rail  14  and right mounting rail  16  are about 24 inches in length. Battery box  52  is about 6 inches in length. The head rail  12  is about 12 inches in length. Those of skill in the art will appreciate that alternative dimensions for the railing  10  are contemplated as being within the spirit and scope of the invention. 
     The shape of the rails  10  as illustrated in  FIGS. 2-4 , are configure such that in coupling to the creeper C, head rail  12 , left mounting rail  14 , and right mounting rail  16  circumscribe a portion of the creeper&#39;s C support structure, frame, or rails (see  FIG. 5  for use with creeper C). Referring to  FIG. 2 , head rail  12 , in a non-limiting embodiment, can be formed from two-piece, angle welded, C-channel or U-channel metal, for example. Left mounting rail  14 , and right mounting rail  16  can be formed each from single-piece, folded sheet metal having positive and negative bend angles, such that the natural side includes the wide bend that forms openings  15  and  17 , as illustrated in  FIGS. 3 and 4 . However, railing  10  (generally) may have other shapes as appropriate, depending upon the shape of the creeper C. It should be understood by those of ordinary skill in the art, head rail  12 , left mounting rail  14 , and right mounting rail  16  are formed, welded, and/or bended in order for the attachment  100  to be attachable, detachable, and re-attachable to the creeper C. 
     As illustrated in  FIGS. 1, 5 and 6 , cut-away portions  80 , allow the attachment  100  to slip-fit on the creeper C by avoiding widely-used creeper&#39;s C caster-wheel mounts (broken lines). Cut-away portions  81 ,  82 ,  83 ,  84 ,  85 , and  86 , as shown, allow the attachment  100  to mate with the creeper C, despite the creeper&#39;s C caster-wheel mounts (broken lines). Those of skill in the art will appreciate that suitable cut-away  80  configuration alternatives are contemplated as being within the spirit and scope of the invention. 
     With reference to  FIG. 7 , attachment  100  includes electrical pathway  90 , in which the power  50  is directed to the light sources  20 ,  70  via the wiring  30 . 
     From the foregoing description it will be apparent that modifications can be made to the rail lighting and lamp attachment  100  without departing from the teachings of the invention. 
     The instant invention may be embodied in other forms or carried out in other ways without departing from the spirit or essential characteristics thereof. The present disclosure is therefore to be considered as in all respects illustrative and not restrictive, the scope of the invention being indicated by the appended claims, and all equivalency are intended to be embraced therein. One of ordinary skill in the art would be able to recognize equivalent embodiments of the instant invention and be able to practice such embodiments using the teaching of the instant disclosure and only routine experimentation.
