Review on Derlights- USB Rechargeable Dog Light for Night Walking & Running - Clip-On Collar Light with Waterproof LED - Safety Emergency Light for Dogs, Cats, Pets, Camping, Biking - 2 Pack by Shay Badger

I love these lights! We mainly use them at night for our dogs in our large garden and can't do without them when we take them out after the sun goes down. It's great not only to be able to track where we post them at night, but to actually SEE what they're doing when we're close enough. These are bright lights and more than enough to replace a flashlight when walking on flat terrain. On a recent trip to the beach with my St. Bernard, I skipped the flashlight and just zipped one up on my jacket and the other on my Saint's collar, and we were ready to go. They have also found many other uses in our household and have proven surprisingly handy more times than I can count. I gave them away as family and friends commented on how good they were and ordered an extra set to keep in my office as a backup to ensure we never ran out of them during the dark PNW winter months. The button battery carabiner will light up beforehand, and these USBs will glow MUCH MUCH brighter. The brightness combined with the fact that they are rechargeable make them perfect for us. We love these lights! I included a video of uncontrollable giggles as we watched our saint and hound dog play tugboat one night. The lights let us enjoy a great show!
