I just got this flashlight for walking the dog at night, and it's really great. Lights up the way, your path, the dog, and it has a rear light (hard to find on any flashlight) to warn cars coming up behind you.
There are quite a few places that sell it, but Amazon seem to have the best prices. BTW, it's a lot smaller than it looks and fits your hand very well. Even comes with batteries.
