PRIORITY CLAIM 
   The application claims a priority date on provisional Patent Application No. 60/946,580 filed Jun. 27, 2007, the contents of which are incorporated herein by reference. 

   FIELD OF THE INVENTION 
   The present invention relates to a rechargeable flashlight and in particular to rechargeable flashlight that is stored within a DC powered receptacle and is available for use in powering additional electrical devices. 
   BACKGROUND OF THE INVENTION 
   Rechargeable flashlights have been used for many years. Typically, flashlights use batteries to power an incandescent bulb. Reflectors around or behind the bulb have been provided to help direct light from the bulb. The flashlight provides a means for illumination in times of an emergency, or for finding items in the dark. To prevent misplacement, flashlights are typically stored in a vehicle glove box. However, with the flashlight out of sight it is not uncommon for the battery source to become stale due to high heat, extreme cold, or age, any of which can render the flashlight useless in times of need. Also, in an emergency the availability of the flashlight being stored in a glove compartment must be recalled otherwise the vehicle must be searched. If the vehicle is an automobile, airplane or boat, attempting to locate a flashlight while operating the vehicle can be quite dangerous. 
   The recent development of light emitting diodes (LED&#39;s) has provided a unique lighting mechanism that can compliment or even replace the incandescent bulb. Use of an LED as a light source in a flashlight has several advantages. Initially, LED&#39;s use less power than incandescent bulbs so that the battery life in an LED flashlight can be greatly extended and/or smaller batteries can be used. LED&#39;s also have a very long operating life, far longer than most incandescent bulbs. Consequently, the disadvantages of bulb burnout or failure, and the need to replace bulbs relatively frequently, are largely avoided. However, battery life of a non-charged battery remains affected by non-use, the actual life of the battery becoming dependant upon surrounding environmental conditions. 
   Rechargeable batteries for use in flashlights is known in art and typically consist of a housing that contains a light source, battery, and battery charging circuit that is electrically connected to a rechargeable battery. Typically, an external connector is provided on the flashlight housing for coupling to a suitable power source, or an electrical charging circuit. While the use of rechargeable batteries in portable flashlight devices has been known for some time, recharging generally is achieved by an external charging circuit, such as via standard wall sockets, thereby limiting the size of the flashlight. If an AC power supply is needed, the flashlight cannot be recharged in a DC powered vehicle unless yet another converter is provided. For this reason, it is beneficial to have a DC powered charger when a rechargeable battery is placed into a vehicle. 
   While a flashlight may be plugged into a DC source a conflict exist because of the advent of cell phones, i-pods, portable e-mail devices, portable CD players, and the like that all rely upon the DC source. The result is the flashlight charging becomes secondary and the flashlight is stored, such as in the glove compartment, in order to allow access to the more commonly used devices such as cell phones, i-pods, portable e-mail devices, portable CD players, and the like. Further, conventional flashlights take up valuable floor space and may become a flying object should the vehicle be involved in an accident 
   Rechargeable flashlights for use in an automotive environment have not been the most convenient to use as they are generally oversized and require various connectors, long lengths of wires, and are generally difficult to use. A flashlight, to be fully functionally, must be capable of complete mobility and not encumbered by size, the attachment of cords, or other ancillary devices. The use of a flashlight on a boat can be necessity should a problem occur after dark. However, the infrequent use of most boats makes for a charging system that may not operate for a month at a time leaving the flashlight with a weak or inoperative light. The use of a flashlight in an airplane is required for night flying wherein a pilot may need directed light for preflight inspection, chart viewing, instrument viewing, and so forth all at a light level or color that will not disturb the pilot&#39;s night vision. Allowing any item to be loose in a cockpit is very dangerous should the plane hit turbulence, however, having a flashlight stored in the baggage area or any area remote to the pilot would render it useless in an emergency. 
   It is also essential that an emergency light is fully charged, as well as being readily accessible. If the batteries are not kept at the optimum charge, the longevity of the batteries is shortened, the operating time is shortened, and the intensity of the light is diminished. 
   The configuration of modern day vehicle, whether the vehicle is an automobile, truck, airplane, boat and so forth includes the use of a cigarette lighter. While most vehicle owners no longer tolerate smoking, the cigarette lighter receptacle has carried on a power source receptacle. The cigarette lighter has been removed and the receptacle now receives power cord connections to various devices such as cell phones, MP3 players, GPS navigation systems, personal digital assistants (PDA s), laptop computers, and so forth. 
   Thus, what is lacking in the art is a portable flashlight that is readily available for use, maintained at the highest battery charge possible, is securely mounted without tools and provides a pass through connector for other device connections.

   DETAILED DESCRIPTION OF THE INVENTION 
   Detailed embodiments of the instant invention are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific functional and structural details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representation basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. 
   Referring now to  FIGS. 1-5 , wherein like elements are numbered consistently throughout. The present invention is directed to the use of a rechargeable flashlight within an automobile. However, use within an automobile is only for a suggested use of the rechargeable flashlight; as the rechargeable flashlight is readily used in trucks, boats, airplanes, or any other transportation device that employs a cigarette type power output.  FIG. 1A  illustrates one preferred embodiment of the rechargeable flashlight according to the present invention with an auxiliary electrical device connected to the electrical output connection, generally referenced herein as  100 .  FIG. 1B  illustrates an alternative embodiment of the rechargeable flashlight according to the present invention with a supplemental light source connected to the electrical output connection. Rechargeable flashlight  100  comprises of a body  01 , which is generally cylindrical in shape and closely resembles the size and shape of a typical vehicle cigarette lighter. The body  01  is preferably longer than the typical cigarette lighter receptacle  02  (not shown). The body  01  has a first end  03  and a second end  05 . First end  03  contains a plug member  04  that is constructed to mechanically and electrically connect with the cigarette lighter receptacle  02 . First end  03  is constructed to resemble a male port in a cigarette lighter assembly. Within first end  03  is housed a plurality of light emitting devices  13 , from herein known as LED, to be used for illuminating purposes when the rechargeable flashlight  100  is unmounted from the charging position within the cigarette lighter receptacle. The plurality of LED&#39;s  13  is to automatically illuminate upon disengagement with the cigarette lighter socket  02  and turn off upon engagement with cigarette lighter socket  02  for charging purposes. In an alternative embodiment it is contemplated that LED&#39;s may be manually switched from an ON and OFF position by use of a dial, switch, or other means known in the art. 
   In  FIG. 1A , the second end  05  of the cylindrical body  01  is constructed with a housing member  09 . The housing member  09  is similar in structure to a typical cigarette lighter receptacle  02 . The housing member  09 , in  FIG. 1A , is ready to adapt to a male end  11  of an auxiliary electronic charging device  47 . The housing member  09  is an electrical output connection for use with an auxiliary electrical device  47  such as cell phone charger. When the auxiliary electrical device  47  is engaged with the housing member, current is drawn from the vehicle&#39;s battery to provide current to both the rechargeable flashlight  100  and auxiliary electrical device  47 . Auxiliary electrical devices  47  include, but are not limited to, cell phones, MP3 players, GPS navigation systems, personal digital assistants (PDA&#39;s), and lap top computer, or the like. In this manner, an auxiliary electrical device can be in use or on charge when the rechargeable flashlight  100  is connected the cigarette lighter receptacle  02 . Alternatively,  FIG. 1B  shows rechargeable flashlight  100  with housing member  09  connected to a supplemental light source and lens, from herein known as backlight assembly  08 . The backlight assembly  08  consists of a lens  10  and supplemental light source or second series of LED&#39;s  11 , shown in  FIG. 4  and described in detail below. The backlight assembly  08  is lit by the supplemental light source  11 ; and the lens  10 , which can contain indicia such as trademarks, logos, corporate, product, or individual names, reflects the supplemental light source  11 . In addition to providing an attractive effect, the backlight assembly  08  also serves as a beacon to enable the user to locate the rechargeable flashlight more easily. 
   In  FIGS. 2 and 3 , the first end  03  of rechargeable flashlight  100  contains at least one LED  13  that is mounted on a LED circuit board  15 . The plug member  04  comprises of a center post  17 , extending longitudinally across rechargeable flashlight  100 , which is held within the first end  03  by a retainer member  19  and an aperture  21  in LED circuit board  15 . A spring member  23  cooperates between the retainer member  19  and an annular rim  25 . The annular rim  25  is formed on the center post  17  to bias the center post  17  in a direction away from retaining member  19 . A battery  27  is electrically and physically connected to the LED circuit board  15  by a second spring  29  and contact member  31 . In engagement within the cigarette lighter receptacle  02 , the center post  17  is compressed during insertion of the flashlight body  01  into the cigarette lighter receptacle  02  so that the end of center post  17  moves second spring  29  and contact member  31  away from LED circuit board  15 . This will allow charging of the battery  27  from the cigarette lighter receptacle&#39;s power source (car battery) while at the same time disconnecting the LED&#39;s  13  on LED circuit board  15  from the rechargeable battery  27 . When the body  01  is disengaged from the cigarette lighter receptacle  02  the center post  17  returns to its original position. The original position of the center post  17  no longer recharges the battery  27 , whereby the second spring member  29  and contacting member  31  couple with the LED circuit board  15  allowing the rechargeable battery  27  to connect with LED circuit board  15 . The connection between the rechargeable battery  27  and the LED circuit board  15  automatically illuminates the LED&#39;s  13 . Stated otherwise when the flashlight body  01  is removed from the cigarette lighter receptacle  02 , post  17  disengages from contact member  31  and second spring  29  thus enabling contact member  31  and spring  29  to electrically connect battery  27  to LED circuit board  15  and the LED&#39;s  13  connected thereon. The light emitted by LED&#39;s  13  are directed through retainer member  19  and emanates through an opening in the first end  03  of flashlight body  01 . It is preferred, that upon body  01  disengagement from the cigarette lighter receptacle  02  the LED&#39;s  13  automatically and instantaneously illuminate. As shown in  FIG. 2 , the battery  27  is supported by a circuit board  33  on the second end  05 , which carries the necessary recharging circuitry as well as an output electrical connection. This output connection is only energized when the rechargeable flashlight  100  is charging within the cigarette lighter receptacle  02 . 
   In  FIG. 4 , an additional element is attached to rechargeable flashlight  100 . The second end  05  of the cylindrical body  01  is constructed with a housing member  09 .
