I know that most of us have a tactical flashlight in out self defense toolkit. But I have found one that is really cool and inexpensive at my local Sams Club. They come in two packs for $15. Serengeti brand, strike bezel, cree led, two stage brightness and strobe function, uses 3 triple a batteries.

Sam's Club-Serengeti LED Flashlight - 2pk

I have bought two packs for a total of 4 lights now. They were much more expensive when they came out so you might want to hurry.

Be careful all and WY6!!
