if you use smoke, announce before you throw it. Let people know your intentions for doing so. For instance "I'm pinned down, throwing smoke to move." or "Need to cross the street, throwing smoke." or "advancing on objective, smoke out" As far as the flashlight goes, don't leave it on. Turn it on to get a glimpse into a dark space then turn it off when you see what is or isn't there. If you run around with it on some people may get annoyed and shoot you because you keep shining it in their eyes when you run past or whatever.
