If your looking for something to paten then here it is!
A head band light with a mercury switch on one side of the band, when you look down the light comes on, when you look up it goes off! I used it years ago for hunting city curbs at night, with street light I didn't need the light to see to search, but I did for retrieving the targets (digging) it worked perfect. The switch could be rotated to adjust the timing of the light coming on and going off.
