“Tactical” means we charge more. I’m a Sheriff’s Deputy for me tactical mean simple and robust. Cell phone size buzzers sound good but in total context. Your flashlight should be fully charged before shift and if you’re in a “Tactical situation” that takes that long to drain your light. Rethink the term, a shift of traffic control isn’t tactical but might actually drain that light. Area lighting might drain the cell but it’s usually propped up on something. But then again the vibrator is a new twist it might actually be a good thing.
