We like this amazing new product because it has so many useful applications. Walk your dog at night? This cool hat utilizes LED technology to illuminate your path to help you pick up after your pet, see approaching people, animals, bikes, and be seen, up to one mile ahead. Great for any night activity in city or county locales. Got a kid? Great safety feature for bike riding at night!  Lasts up to 90 hours on 2 included  lithium batteries (not expensive to replace).
