I used what ever hand held light was on sale at the sporting goods store sites . I kind of liked the lower powers and used a blue cover instead of the red kept it higher then there eye level so as not to put it directly into their eyes . You just need to see their eyes and identify them so you know what your going to kill . As you don't see like it's day light practice helps you to know how to hold the light and what it is that your looking at . I liked to know my hunting area well during the day time so I knew what was behind my target in the night time no stock , homes , roads that some one may be setting on with their lights off .
