I keep a Mag-Lite in my car for a couple of reasons. First, I might need a flashlight. Second, it could be used to knock a dirtbag in the head. I found a nifty accessory for my Mag-Lite at SHOT Show. It's called Bust A Cap. It's a tactical glass breaking piece that replaces the existing end cap of the Mag-Lite. It turns the flashlight into a "break-in-case-of-emergency" device. You never know when you might need one.
