Pelican Progear 1810C LED Keychain Flashlight - Ultra Bright, Compact & Waterproof for Emergency, Camping, Hiking & Everyday Carry (EDC)

I have two of these. One on my keychain, and the other attached to my dog's leash. You can find brighter personal flashlights, BUT they're much larger and they cost more. This thing is small. You won't even know it's in your pocket. It's small and light, but it's very strong and durable as it's metal. The light is bright enough to illuminate anything in front of you or in your immediate area, and honestly, that's all this is meant to do, so it is doing it's job. I had to replace the small watch battery on one of mine after about 3 years and it still works fine. I would recommend this product.
