Statistically speaking, most home invasions still come in the night. My carry weapon is on the table by the bed & I can put my feet on the floor & my hand on the gun w/ my eyes closed. Yes I practice that & teach it too. Even so the tiny green spost are a great reference point in the dark. They make me able to put my hand on the grips in almost a perfect draw grip evenin the dead dark. Flashlights are great if yo have a good LED that you can suddenly blind a BG with by sudden ON. A regular flashlight, on, walking down a dark hall,
Might as well be loud counting 1,2,3, here I come ready or not. I shoot enough that I down a home hall (30 ft) or across a room (half that) If I can iD a target as BG I can make a personal defense hit with one hand point & shoot if necessary. Even so the little green dots are, again, good reference points. I would not be w/o them.
