The cover fell off after having it on my dog for about 5 min. Then the ring came undone from her collar and the flasher fell to the ground. I had to put a new ring on it, but the hole is so small it will only take a thin, flimsy ring. Not the best design for a dog that loves to play. I had to tape the cover back on as well becuase it kept falling off...no the best quality product for the $.

Super easy to use and attach to collar or harness, and super easy to see!

I like the Beacon light as it is pretty bright and helps me keep track of my boy while he is working SAR at night. I have his light on his shabrack so it isn't distracting for him while searching. It is nice to have the different lighting options on the light as well. So far I have not had any problems with water getting into the light housing while swimming. Thanks Ruffwear for another great product.

definitely bright and visible. But not watertight in a rainy climate. We have had three of these fail to work after being worn in a rainy wet field (not swimming). Also, they are a bit bulky and tend to swing down under the dogs chin. My dogs seemed bothered by this flashing light under their chin. I am seeking a truly rain resistant, visible light that will stay up on their collar on top of their necks, out of their view. This isn't quite it.

These lights work well. I have to admit I've never sent my dogs into the river with them, however, I don't remember seeing that they were waterproof. I wouldn't expect a light to work after going into the river unless it professed to be waterproof. They work great, hook on the collar perfect, and are good for low light running. Also good if you can't see your dog at night.

After a few forays into the river with my lab, the Beacon went from solid to flashing. It did not respond to pushing the button. At home I had to pry off the front and remove the batteries. There was water inside the casement which I wouldn't expect from a 'watertight' product. Also the metal ring is too easy to bend and, if caught in the underbrush, would easily come loose. I paid $20 Cdn for this product and was relieved that I was able to get a full refund. It is bright, brilliantly so, but not suitable for an active dog off leash who jumps in the water for a few minutes.

Great must have for night time and low light activities.

With a small black dog seeing him at night is almost impossible. Your light has made all the worry go away. I have seen him a 1/2 mile away when the night and for made it hard to see my hand in front of my face. Thank you for the light and the wonderful light loops!

It helps keep my dog from being hit by a car on our early morning walks.

Love the beacon. We take Zach out for his before bed bathroom run in the wooded yard, and we can see where ever he goes. It's hard to aim a flash light at the ground for my feet and keep an eye out for Zach too. The beacon solves that problem

I love these lights they are bright when we let them out on vaction at Cape Cod . it is very dark there at night and we know where they are

Love the beacon. We live in an area where there are no street lights and the high visibility of this little light gives me peace of mind when walking my big black dog at night. Ruffwear customer service is exceptional.

I'm giving this a 5 star because I've bought lots of junk lights at the pet store, and this is the best out there. We run at night in the cold Wisconsin winters, the lights clip right onto the loop of their coats (also purchased through Ruffwear) and it couldn't be a better design. I do agree with previous ratings that the ring isn't as secure and bumps around (caused the outer case of the light to fall off once) but there is no need to ever use the ring - even when they aren't wearing their coats that has the handy loop attachment, I've found that the clip does fit quite securely to thier collars - even a thicker collar. My boxers are quite "ruff" with thier gear (they're maniacs on the run - 5miles/4 days wk), so I think they're the best sort of testers for this sort of product. This light is heavy duty and if my boy Pacino can't break it, it's pretty awesome for any dog out there.

The Beacon is a great way to maintain visibility of your dog at night especially when they are playing off-leash. Bandit almost got lost one time at night so we made sure to acquire a light to keep track of the curious little guy. My only complaint is that it is a bit bulky and the clip will only go onto a thin collar. We secure it with a small moutaineering clip but it still bangs around a bit when he is playing. Overall, a great product!

I need to be able to see my dogs at night. My Jack Russell is on the go the minute I turn him loose and my Aussie is a Search dog. The light in the flash mode allows me to keep track of both. I wish I had a way to attach a small caribiner directly to the light body for quick attachment and release. Great light overall.

We love The Beacon. We go out for walks early in the morning and at night. It's great because drivers see me walking low to the ground and slow down for us. Also Shannon can see me when I go into the bushes as I'm a dark brown color it's easy to keep me in sight she knows where I'm at. She likes how The Beacon has 3 types of light settings. We use the 1st setting that always flashes as it seems to gets the drivers attention. Since you can clip it on to anything we keep it on my harness so we don't forget it and it's weather proof too I've already tested it out rain and snow! We love it!

I have looked for a lot of ways to light up my dog in the dark and this is one of the best products that can be attached to my dog. I am still looking for a bright blinking collar like the VisiGlo, but that product is not made for big dogs like mine I wrecked two of them already. The Beacon combined with the track jacket and it being attached to the loop on the back of the track jackedt makes my dog very visible from quite some distance. I had an incident once where I lost the red cover from one of my beacons, maybe due to the cold here in Alberta or because my dog likes to bounce around I don't know but Ruff Wear's customer service was fantastic, they handled this very generously and sent me a replacement.

Light is very visible, attaches to light loop if you have a Ruff Wear coat. Also you can change the light pattern from blinking, constantly on, etc. I like the fact that it is well made and waterproof.

the improved model is really good

Great illumination--it's saved owner and dog several times on dark New England Winter walks. Keep extra batteries handy, as this is a very bright light, and you can see a noticeable dim when you need to replace them. I bought The Beacon at REI.

Do yourself and your dog a favor and put the beacon on him whenever he goes out at night. The beacon alerts drivers long before they get close. No dog should be without one at night!

We love the beacon. It is great to have on during heavy snowstorms. The only problem we find is the clip does not secure it to the light loop. We almost lost the lights several times when they came loose. The ring is the best way to secure the beacon.

Very bright and works really good. Worth the price and 99.99% will be happy with this lite. Feed back on differnt or even better lite and way to attach...If possible would like lite that has a better way to attach it to the Ruff Wear lite loop on the jackets. The clip on this lite and jackets does work good on some of the Ruff wear jackets....but is hard to attach. I all most lost one lite in the woods on Climate Changer Fleace jacket (I own every Ruff Wear jacket made and own sevral of these lites for each jacket)...good thing it kept blinking this time and the snow wasn't very deep and I wasn't very far when it came off. The key ring loop can be used on this lite but that makes the lite not as visable cause the lite lens is only visable when looking directly at the lens and leaves a bigger blind spot. If possible I would also like a lite lens like this that can be seen better from the all sides or more angles when its on and or mounted on a Ruff Wear jacket.

Love this light-especially the different attachment features and light settings. It would be great if it were a little lower profile/bulky, but all in all a very sturdy and durable light for dark hikes and walks.

Awesome product, with nights getting dark fast this is a must. The three settings allow for different types of lighting for the amount of distractions around. I was able to put one around the toy and throw it out in the field and watch it come strobing back in the dogs mouth. This makes night events fun!

I have referred a number of people to this product. It's sturdy, has light up options (quick flash, slow flash and constant light) and super bright. I live on acreage and after trying a number of other light up products it's such a relief to be able to see my *black dog*. LOL

Bought 2 of these when visiting the USA 14 months ago. These beacons are really good. Easy to dismantle and dry out when they get a bit soggy. My 2 love their "flashers" for a night time walk and I always know where they are
