While I have a number of high quality gun courses under my belt I have no formal training with low/no light shooting. In my courses the point that most defensive scenarios occur in less than optimal lighting is emphasized. In addition, the difficulty and potentially dangerous aspects of clearing rooms was also drilled into my noggin'. However, there is always the potential that I might have to clear my own home at night time. With this in mind, what are your thoughts about a gun mounted light be it a pistol or AR/AK type gun? Do you keep it always on or do you manually do quick on/off's? Strobe it??? Thanks PS Eventually I will get some training under my belt but until then I will appreciate your thoughts or links to shooting guru's thoughts.
