I have a good one.....carbide lamps.......the kind miners use to wear on their hats ....and old brass bicycle lights ran on carbide.......carbide is a little rock when water drips on it it releases a gas that burns very bright......every time we were in wilderness areas the carbide lamps would be lighting our way WEEKS after all our batteries were dead.......the old bicycle lights had a glass lens so it could be used as a good headlight.....they have a long historical association with bikes.....the miners version has no lens but great for camp use.....a can of carbide will give you months of light......a cyclist shouldnt leave civilization with out one
