Or you can get a NEBO CSI Tactical model flashlight. You can easily find them for under 20 bucks. They have 8 LED lights and a laser pointer, and they're made of metal. They're great for temporarily blinding an attacker, even in daylight. The ends have a strike bezel on them, which is essentially just a specially shaped ridge that makes it hurt more if you smash it into the side of an attacker's skull.
They don't have the lumen output of a 300 dollar Surefire, but I've looked into my NEBO before and it *hurts.* And mine isn't even the tactical model.
A few other advantages are that you can fit them in your pocket, and you can easily get away with taking them just about anywhere since it is just a flashlight. Heck, even the UK citizens could probably get away with carrying one of these around.
