2 Pack Dog Collar Light, 4 Modes Clip On Dog Lights for Night Walking, Glow in The Dark LED Pet Collar Charm, Rechargeable Pet Camping Essentials for Nighttime Running, Cycling, Hiking(Black)

They work great; they hold their charge. It's a pretty good, bright light at night, and I actually live out in the woods, so it's a plus that I can actually see it on the dog at night. It's easy to charge and easy to change from collar to collar, and it's been very dependable. I've had this for several months now.

Very bright and easy hook up and removal. I hook one onto my German shepherd puppy’s chest ring on his vest. Two pack is great and the price is right. I’d buy them again

These collar lights are bright and ideal for the pitch black nights and mornings. The idea that it’s a two pack is great because you can have one fully charged to switch at all times.

These work very well. They stay charged a long time. They are fairly bright. Down side... the plastic clasp breaks off after a month or so of walking the pup (Catahoula). Wish these were more durable. Gone through several packages. Luckily not too expensive.

These lights are extremely bright, have different flashing patterns, and a very white steady option as well. In my own yard, when I let the dog out, I can find him wherever he goes. When walking, the light alerts drivers. Very safe.

I use this for my purse and backpack. I put one inside my purse. I have it on an inside key clip. With a soft push, it easily turns on so I can find things in my purse. It has different brightness settings. I clipped the second one on the outside of my backpack. It’s perfect for walking outside at night. I set it to strobe for safety. It’s good quality. It clips easily and stays put. The size is just the right fit. I can easily see this working to keep dogs safe. They’re low to the ground and some drivers don’t drive carefully. These lights can save lives - canines and humans.

EDIT: After submitting my initial review of these items, I'm forced to edit that review with even worse information. As of today, neither one of these lights will take a charge and neither one of them work at all now. Such a joke. I would highly recommend that nobody purchased this item when there are so many others to choose from. Why Amazon is choosing to make this a product worthy of "Amazon's Choice" is beyond me'. These are pure junk and would not be the worth the purchase if they were giving them away for FREE. PURE JUNK. These will be returned this week for a full refund. Im really sorry I chose this particular brand of item of all the ones available. But they were supposedly "Amazon's Choice". Says to contact the seller before writing negative reviews. Not sure how to do that, hopefully they will see this... In a nutshell, these seem to have no battery life. Additionally, there's no indicator light anywhere to let you know that the lights are even taking a charge, or are fully charged after they are no longer working. They have a very short battery life and mine seemed require recharging frequently even though they are used only 10 minutes at a time while my dogs are leashed and going out after dark. When charging, one seems to charge okay, but the other will not take a full charge regardless of how long it's left on the charger. I see they are now on sale for even less than what they were when I purchased them, but still don't see these as a bargain if they all work the same as the 2-pack that I received. Going to make arrangements to speak with Amazon and neither return them or throw them in the trash.

Works as says. Leave on straight white light, hang from front of collar on D ring, dog lights his own path at night, easily see if getting into something on night walks, plus makes dog more visible to cars! Edit: liked, but 1 stopped working 2nd night. So far other still working.
