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 Jane Crawford

Just what I needed to make my dog more visible at night for safety and also to highlight anything he puts his nose in plugged. This works great on both fronts. I clip the flashlight to the front ring of her harness so it hangs down, illuminating the floor in front of her. Rechargeable flashlights are much better than batteries. They come in a set of 2 which is perfect. I use one and keep the other in my bag in case I run out of charge on a long walk. Usually they only need to be charged once a week. Durability is good considering how cheap these lamps are. The weak point is the charging connector, so be careful when plugging it into the socket. I recommend marking which side is up on the USB cable. The charging port on one of my flashlights failed after about a year; He broke the circuit board and disappeared inside. I emailed the company and they sent me a replacement straight away. Highly recommended, good value for money and the seller stands behind their product.
