Target identification is a must, if a light isn't on, you need a flashlight, either way you are going to be visible. A bright led light in your unadjusted eyes disorient you, even in daylight.
Your flashight isn't going to make you an easier Target unless you are in a combat situation and and at range, even if you were, I've yet to see a light that didnt have an off switch, this isnt call of duty. Find a way to attach a light to your primary home defense weapon. You can't undo the mistake of miss-identifying a loved one.
