Tehuacana gave me one of those caps with the light on the brim, invaluable for cave explorations.
Unfortunatly I'm between caves right now so I was looking for another use for it....and I found one....
It's invaluable for raiding the fridge in the dead of night without having to turn on any house lights....
It also has a flashing RED function that is a great warning not to eat too much.
I was told when they gave us those to give out at the public awareness meetings that the reason it had two and four white lights was for bathroom use at two in the morning. Two for the younger guys, four for us old people (need more light), and the red ones if there was an accident. Glad you found another use for it. I'm always being told I need the red ones,I forget to raise the seat.
