No night lights on in the house here. I'm sort of an energy conservationist. For those wondering or debating on flashlights, weapon mounted or otherwise------let your ears tell you where to aim first in the total darkness. When you go to identify with the light, aim high or to your eye level----then turn on the light momentarily---in total darkness, this instantly blinds whoever it is you're lighting up, and there is a sense of shock when that happens. Flash, assess, and move or shoot! This way you will limit your exposure to becoming a target with a light. The possible BG who has just broken in will be listening also, but more than likely will be hearing the sound of his own heartbeat. You are a soldier in your own fort---turn the element of surprise around quickly to your favor. I like my weapon mounted light for these reasons on my house gun. Integrate it into your practice scenarios---practice often, and it's employment will become second nature. I'll have both hands on my pistol----not one and one.
