Prefer Streamlight, Sure Fire, and Insight Technologies lights. I have a standard issue rechargeable Mag light mounted inside the car, but it really hasn't been all that reliable. It tends to either not charge when in the holder, or not turn on when the button is pressed. Maybe it needs a good cleaning. At 0300 in the pitch dark, I will always be using my Sure Fire light, with a small Streamlight in my upper vest pocket as a backup. I scan low, high, and 360, looking not only for 2 leggers, but snakes as well. The lower power lights don't illuminate snakes, gators, wild hogs, and big cats like the tactical lights do. I also have a Streamlight pencil with green LED which has survived for a good 4 years now.
