In this way you will have brief flashes, say every one or two seconds, and battery life will significantly improve. There's many online calculators to do that, and will tell you the values for the capacitor and the two 555 resistors. Then you can obviusly use a fatter battery of course :) To make battery life even longer you have to calculate a longer period for the 555 and a shorter duty cycle.

Could you help me on that.
