  • Patent number: 6722770
    Abstract: A flashlight in a housing of given size dimension to fit within and under a shoulder epaulet on an article of clothing worn as part of a uniform by a person engaged in law enforcement or emergency medical service activity, for example, with a fastener at a top surface of the housing in the nature of a clip to secure to the shoulder epaulet in providing hands-free operation. A plurality of light emitting diodes along with a mirrorized surface increases the intensity of visibility through a front end of the flashlight in viewing an area, with a plurality of light emitting diodes generating a rearwardly extending beam as a warning light to oncoming vehicular traffic, either with or without a like mirrorized reflector.

  • Patent number: 6015217
    Abstract: A flashlight in a housing of given size dimension to fit within and under a shoulder epaulet on an article of clothing worn as part of a uniform by a person engaged in law enforcement or emergency medical service activity, for example, with a fastener at a top surface of the housing in the nature of a clip or otherwise, so as to secure to the shoulder epaulet in providing hands-free operation, and preferably generating its light beam through a rotatable front end of the flashlight which both adjusts the angle of the beam, and which acts as the on-off switch for the flashlight. In a second embodiment of the invention, a flashing light beam could also be provided to illuminate through a back end of the flashlight, in giving a stroboscopic type of warning light to oncoming vehicular traffic to reduce speed in nearing the scene being approached.
