Too often we look for lights that are lighthouse beacon bright, and the usefulness of small, dimmer lights is forgotten. The SpotLit is not just for the dogs. Here's my experience with these little lights: 1. Use as a marker light on your pack or tent, set to blinking to find your way back from "the facilities" - amber is good for this. 2. Remove the two CR2016 cells and replace with a single CR2032 for a dimmer, but longer lasting light - especially amber, also green, and even white are good for this, turning this little gem into a dandy tent or hammock area light to hang that doesn't blind you when you need to see in the middle of the night. 3. The green with either the two CR2016's or a single CR2032 is adequate as a "trail light" in the middle of the night to find your way to and back from the "facilities" and illuminate the area when you're there. The SpotLit's come apart with a bit of prying of the back cover to fiddle with the cells... don't be anxious about it. It does take a bit of force to actuate the push switch on that back cover, so this isn't easy to work for children or those with weak hands. With a similar ability to change from two CR2016's to a single CR2032 for dimmer but longer light, the SpotLit takes the area light trophy while the Photon Microlight II takes that same modification and the trophy for the night vision green (or amber) micro trail light you can wear around your neck. I've gifted these to friends for use when camping.

A little big for a jacket zipper, definitely bright enough, but great on the dog collar to give them that added safety. Some great colors to choose from I got green and orange. Can be a bit difficult to turn on, especially wearing thick gloves but doable.

Great product. Bright light and sturdy. Had other similar lights, but they kept turning off when our dogs stopped to shake. We've been using these for 3 weeks now and have had no problems.

Nice lite for night walks . A bit big for our corgi dogs. THE balls drag the ground. The spotlights would be great for regular sized dogs.
