It's not uncommon for me to ask people I know who carry "What do you have on you?" when privacy lends itself... and I have given probably hundreds of lectures over the lack of a handheld flashlight. "Why don't you have a light?" is the one thing that gets a few excuses. "Lights like you carry are expensive." "Batteries don't last long enough." "123 Batteries are expensive." "I carried a ...... but it just didn't seem bright enough." "I don't want to carry a big flashlight around with me all day." Those are what I get most commonly.
What if there was a new line out there that made every single one of those excuses invalid once and for all?
