LED Dog Collar, USB Rechargeable, Waterproof IP68, Multi-Colour Light Up Safety Collar with 5 Colour Options- size S

Decently bright and noticeable. Collar has 3 light-up options: static light, fast blinking, and slow blinking. I don't like to use the blinking options though because they hurt my eyes, but otherwise they help with visibility. Used this during walks at night and it has been helpful for others to spot my dog. The collar, itself, is incredibly strong and doesn't feel like it'll wear off nor break, at all, as well as the buckle feeling strong enough to not be loose. The collar is also reflective, and when seen by car headlights, the collar really shines. So, eventually when the light stops working, the reflective collar itself would be helpful in being noticeable. I like that the collar is rechargeable, instead of having to use batteries that need to be replaced. You can see from the video that my German shepherd absolutely LOVES her new collar :)

We ordered the medium-large size for our mixed breed adult dog who weighs in at about 55 pounds and there was plenty of room for adjustment. The collar seems to be well-made of a durable nylon material, and the buckles and other attachments are made of plastic except for the leash D-ring which is metal (zinc?). The LED lighting unit is basically a small box that is integrated with the collar's clasp. The LEDs have three settings: solid on, fast flash and slower flash which are selected by a push button on the LED/clasp assembly. The LEDs are VERY bright and are four different colors but they all flash at the same time so there is no specific color selection or other pattern available. We live on a large rural property and like to let out pup run freely within the fenced perimeter, so this collar makes it really easy to see where he is at night when we let him out. The collar is fairly wide and nice looking, and the overall construction and material quality is comparable with other collars we have used previously. If you need a high visibility collar for your furbaby for nighttime walks or just to be able to see it at night, this collar will do the trick. Recommended.
