I'm sorry, I am missing the gene that makes people believe flashlights are better than bike specific headlights. The proponents only prove my point when key elements of bike practicality are missing in the flashlight wheelhouse. Flashlights even today are optimized for handiness. They have abysmal runtimes because you are not expected to be using them more than a few minutes at a time. The strobe mode in a flashlight is an SOS, HELP ME function which, well how long before you either die, or are rescued do you need the SOS function to last? This could have been a really short thread. 2nd post should have been "Get a bike headlight". Problem(s) solved. Oh, not even going to accept that it is acceptable to want to put AA batteries in landfills every week. If a flashlight can be built better than my MagicShine I want to see it. I might buy it. To use around the house!
