     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to the field of law enforcement and, more particularly, to an improvement in the uniform epaulet-coupled emergency flashlight of my U.S. Pat. No. 6,015,217, issued Jan. 18, 2000. 
     2. Description of the Related Art 
     As my prior patent indicated, law enforcement, military police, corrections officers, border patrol, etc. usually carry flashlights of a type which can be grabbed by persons being questioned, and used as a weapon against an interrogating officer. My above patent described a flashlight which allowed the officer&#39;s hands to be free for use, and to enable the officer to react quickly to any attempt to injure or seriously place him/her in harm&#39;s way. Such flashlight then placed the officer at an advantage, rather than at a disadvantage. 
     As therein described, the flashlight was worn as part of a uniform, securable to a shoulder epaulet. A front end was rotatable upwardly and downwardly to generate and spread a light beam in use—or to be hooded closed, concealing the nature of the housing as an illuminating source when not being so employed. A flashing light was additionally included to illuminate through a back end as a rearwardly projecting beam in serving as a warning to oncoming motorists approaching from behind. 
     SUMMARY OF THE INVENTION 
     The present invention will be appreciated to extend the concept of this flashlight still further, in enhancing the quantity and quality of the light both forwardly and rearwardly, yet without increasing the size of the flashlight to any meaningful extent. At the same time, the flashlight of this invention will be seen to provide its operation in a variety of outdoor conditions—and especially in harsh environments where inclement weather conditions exhibited a tendency to rust or otherwise wear individual ones of the component parts of my earlier design. Realizing at the same time that uniforms worn by various law enforcement personnel both in the civilian and military fields oftentimes may differ, the flashlight of the present invention will be seen to be one in which a snug fit is insured on virtually every uniform design in use today. 
     Thus, and as will be seen from the description below, the enhanced uniform epaulet-coupled flashlight of the present invention incorporates a mirrorized reflector coupled with the front and rear lenses to increase and intensify visibility. At the same time, the single candle bulb utilized in generating the forward extending light beam of my prior construction is replaced by a plurality of ultra-bright light-emitting diodes (LEDs), while the halogen bulb utilized in generating the rearward extending beam is similarly replaced by a plurality of such LEDs—preferably of differing color combination to provide an increased observer awareness. Rechargeable nickel-metal hydride batteries are employed instead of double-A or triple-A alkaline batteries—preferable even to rechargeable ni-cad batteries. Additionally, and as will be seen, the rotating front lens which acted as an on-off switch for the flashlight itself is modified to be a 90° rotating head, instead of the 180° rotating head as in my earlier design—both for purposes of reliability in operation and so as to present less of a metal rotating clip in operation, which analysis has shown might rust or otherwise be adversely affected when used during rain, sleet, snow or similar inclement weather conditions. 
     Able to alert oncoming motorists of an officer&#39;s presence with a preferred stroboscopic light configuration in its rear, the flashlight of the present invention will be appreciated to be one offering upwards of 100,000 continuous hours of life without the need for a bulb replacement. When packaged along with an epaulet extender, the flashlight could then be secured with a wide variety of uniform designs.

     FIGS. 9 a - 9   c ,  10   a - 10   c  and  11  are disassembled views of the components parts of the improved flashlight of this invention, helpful in an understanding of its advancements over my previous construction. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     In FIG. 1, reference numeral  10  identifies a uniform shirt of the type worn by law enforcement personnel in the spring or summer, or a uniform jacket worn in the fall or winter, along with the shoulder epaulet  12  usually found at the shoulder  14 —and if not so included, then to be added there in accordance with the teachings of both this, and of my earlier, invention. As also shown, a flashlight  20  in a housing  16  is intended for placement within and under the epaulet  12 , with a fastener  18  simplified greatly at its top surface  21  to be secured to the epaulet when so inserted. Selected of dimension to fit within and under the epaulet  12  in a manner to be fastened to it as by a clip in a snug manner as to be further described, the housing  16  may be of generally rectangular cross-section. In a preferred embodiment, the housing  16  may be of a width “W” of the order of 1½-2½ inch and of a thickness “T” of the order of ¾-1 inch. Such housing  16  may be fabricated of plastic, or any other appropriate material, and of a length “L” of the order of 3-5 inches. 
     FIGS. 2-8 more particularly illustrate views of a preferred embodiment of the flashlight of the invention in assembled form. More specifically, FIG. 2 illustrates a front perspective view of the housing  16  showing its front lens cover  30 , its securing clip  32  and an on-off switch cap  34  for energizing LEDs in generating a rearward extending beam. FIG. 3, on the other hand, is a rear perspective view of the housing  16  showing a rear lens  36 . A top view of the housing  16  is shown in FIG. 4, while a bottom view is shown in FIG. 55, where reference numerals  95  represent a pair of screws in fastening the housing together. The top cover of the housing is shown at  36  while the bottom cover is shown at  38 . A plurality of vent holes is provided in the bottom cover  38 , as at  97 . In the embodiment of the invention shown in FIGS. 2-5, the length “L” was selected to be 4.450 inch and the width “W” was selected to be 2.083 inch. FIG. 6 is a end view looking at the front lens  30  of FIG. 2, while FIG. 7 is an end view looking at the rear lens  36  of FIG.  3 . FIG. 8 is a left side view of the housing  16  of FIG. 3 with its front lens  30  open in a downward position, and with reference numerals  40  and  42  identifying a spring and a pin, respectively, for fastening the clip  32  to the epaulet  12 . A housing for the front lens  30  is shown at  44  for opening and hooding the front lens compartment. In the preferred embodiment of the invention, the overall thickness for the housing and the clip, shown as “T” was selected to be 1.127 inch. 
     FIGS. 9 a - 9   c  are helpful in understanding some of the improvements of the flashlight of this invention as contrasted with that of my earlier design. FIGS. 9 a  and  9   b  show the front lens “on-off” switch as being rotatable only 90° in exposing three ultra-bright light-emitting diodes  50  in providing thousands of continuous hours of life before the need for replacement. In FIG. 9 a , the LEDs  50  are exposed, while in FIG. 9 b , the LEDs  50  are hooded closed. Rotating the lens cover  44  from the position shown in FIG. 9 b  to that shown in FIG. 9 a  switches the LEDs  50  “on”, while rotating the lens cover  44  in the opposite direction turns the LEDs  50  “off”, besides hooding them. 
     FIGS. 9 a  and  9   b  also show three LEDs  52 ,  54 ,  56  behind the rear lens  38  to provide a stroboscopic effect when energized, as by the depressing the rear cap switch  34  of FIG. 2 in actuating the plunger type control  58  of FIGS. 9 a  and  9   b , which rests beneath it. To heighten even more the stroboscopic effect, these LEDs  52 ,  54 ,  56  may be of differing colors, one from another, as by having the two outer ones illuminate “red”, and the inner one illuminate “white”. FIG. 9 c  also shows a nickel-metal hydride rechargeable battery pack  60 , of 4.8 volt. As will be appreciated by those skilled in the art, nickel-metal hydride batteries are able to avoid many of the charging memory problems associated with nickel/cadmium rechargeable batteries, and exhibit an average one week&#39;s time of standard use once fully charged, before needing another charge. Recharging is by way of a standard pin shown as  62  in FIG. 9 c , accessible by removal of the cover  64  in FIGS. 3 or  8 . As FIGS. 9 a - 9   c  illustrate, only the front cover  44  is rotatable in acting as the “on-off” switch for the illumination of the forward facing LEDs  50 , with a tapping of the cap  34  being sufficient to energize the rearward facing LEDs, and to then turn them “off”. 
     Pairs of mirrorized reflectors are added with the invention, coupled with the front and rear lenses to increase and intensify the visibility of the light emitting diodes employed. With FIG. 10 a  representing a perspective view of these reflectors  80 , and FIG. 10 b  and  10   c  representing top and bottom views respectively, the three apertures provided  82  are sized to encircle the LEDs in providing a further reflective surface for their illuminations. With the mirrorized coating being on the top surface  84  only, the end result is an intensification of the light beam generated downwardly on the paperwork being reviewed by an investigating officer, and an intensification even more of the rearwardly produced stroboscopic effect alerting the oncoming motorist. With the LEDs offering up to 100,000 continuous hours of life and more, and with the nickel-metal hydride batteries affording significant increases in battery life, a 30%-50% reduction in electrical consumption is further offered in enhancing operation. 
     Recognizing that not all uniform shirts or jackets may come with an epaulet of length to permit ready insertion of a flashlight of this type under it, the flashlight of the invention could be packaged along with an epaulet extender to ensure a snug fit on virtually every uniform. Such an extender is shown in FIG. 11, of approximately 1¼ inch length  90  and of an elasticized composition in allowing its opening  87  to receive the already present button on the uniform, and a button  89  to couple to the shirt or jacket. 
     While there has been described what is considered to be a preferred embodiment of the present invention, it will be readily appreciated by those skilled in the art that modifications can be made without departing from the scope of the teachings herewith. For example, in a manner similar to that set out with respect to the flashlight of my U.S. Pat. No. 6,015,217 design, the improved flashlight of this description could be used by emergency medical service technicians or by others besides law enforcement personnel. And, in similar manner, while the invention has been described utilizing light emitting diodes in groupings of “three”, other combinations can be employed, of either the same or differing colors in projecting a rearward beam stroboscopically or otherwise, and other than three light emitting diodes could be used in generating the forward extending beam in illuminating an area while permitting unfettered use of one&#39;s hands. Also, while mirrorized reflectors have been described as being highly advantageous when employed with both the forward and rearward facing plurality of light emitting diodes, either one could be eliminated and yet the flashlight still provide enhanced operation over that previously available. For at least such reasons, therefore, resort should be had to the claims appended hereto for a true understanding of the invention.
