Unironically I'm completely habituated to using the flashlight on my Fenix 7 every night instead of switching on lights when I get up to take a piss, walking up the stairs or whatever. It's the most useful feature on the watch by far. It was a gift, I never would have bought it though and would be completely happy if a normal protrek came with such a light.
At work I had an old model olight mini headband light in my emergency kit but never was retarded enough to have to use it.
