Review on USB Rechargeable LED Beanie Hat: Hands-Free Headlamp Cap with 4 LEDs for Unisex, Ideal Winter Knitted Night Lighted Hat Flashlight - Perfect Gifts for Dad, Husband, Him & Her by Steven Loy

I bought one for my husband as a Christmas present and then I bought another one for myself because it was so good! There are three different light levels and it can be easily removed for charging. We've been wearing hats walking our dog for weeks and still haven't had to charge the battery! It's bright enough to see what you're doing in the dark and great for walking our dog when it gets dark so early. I'm looking to buy a pair for dog owners who don't wear anything reflective in the dark.
