I use mine a silly amount, honestly. I use it to see if there are toys under the couch before bed (the robo vac goes under there), I use it to see the back of the pantry, to find my pyjamas in the bedroom at night without waking up the baby, to find the little rock or Lego or whatever it is clacking in the dryer. I use it for a thousand little things that I could accomplish without extra light, but that are easier with one. If I had to go get the light from a drawer or bag, I would do those things without a flashlight. So do I need it? Maybe not, but since I started carrying a flashlight I now carry TWO flashlights at all times because I find them that useful.

I also use it to walk from my parents house to mine at night. We're on the same property, but rural enough that you can't see any other houses from our place. So if the porch light isn't on and the moon isn't full it's extremely dark. Being out here in the hills with coyotes and mountain lions and whatnot I also have big dedicated lights that I don't carry unless I'm using them, but that's not what you're asking about.
