  • Cap mounted light
    Patent number: 6895602
    Abstract: An illumination system for a hat is provided. The system includes a light pivotally connected to an attachment mechanism constructed of hook and latch material. The hook and latch material is provided around an adjustment band of a typical “baseball cap.” Batteries and a touch sensitive switch are coupled to the light with the touch sensitive switch facing inward. The cap is usable in its standard orientation during the day to shield the suns rays from the user's eyes. At night, or indoors, the cap may be reversed. Whereas in the standard orientation the touch sensitive switch is blocked from contact with the skin by the user's hair, in the reversed orientation the touch sensitive switch contacts the user's forehead, thereby actuating the light automatically for use.
