Review on HiGuard LED Dog Collar: USB Rechargeable Glowing Lighted Up Collar for Small Medium Large Dogs - Water-Resistant & Cuttable TPU Safety Collar Lights by Brittany Jackson

That's exactly what we need! Our black haired dog cannot be seen at night - a big problem when he is off leash! I ordered 2 other collars but had to return them as they were too big and uncomfortable for him. He's a Yorkie mix - thin neck - and the light from those collars practically blinded him! I didn't want to buy this one because it looked like one of those LED sticks you see on New Year's Eve, but I was wrong! It's perfect: it can be cut and adjusted to the dog, it doesn't bother him at all, and the collar light is easy to see even between the bushes in our park. Charges well and easily, lasts several hours, durable. We've been using it for over 2 weeks now and are very happy with it. If things change over time I will update. But so far so great!
