This is a great dog collar with a LED light in it. I bought it for my sister's small puppy however, the collar is too big and too heavy for a small puppy. I decided to put it on my work bag. I cut it out perfectly to fit my bag. I work nights so the blue light illuminates my bag perfectly. I used it for couple weeks already and it works perfectly. It is rechargeable so I don't have to waste any extra money on batteries. #shinefordogshttp://www.amazon.com/dp/B01CLJ9VLG
