I think it would be great to have a voltage reading mode so as to estimate one’s battery life. Alternatively, maybe someone could help me learn how to read the step down. I.e. it happens at X voltage, which means you have Y percent battery left.
Speaking of bicycle lights...since the Clicky will eventually go away, may I suggest the next Bicycle Light have a variable speed strobe setting which utilizes the rotary dial to adjust the speed?
