[2 Pack 3 Modes LED Safety Light Red Flashing with Free Clip on Straps Sport Running Warning Strobe Tail Lights for Dog Collar, Walking, Cycling, Bike, Helmet,Etc(Batteries Included)

Not much to say about them. They're bright, and they have multiple flash patterns (including steady on). The attached clips are low-profile and hold well.

I like the lights i recieved but they are blue. They are supposed to be red. That sucks but i guess i can deal with it.

These work great . Attached to my dog’s harness with the Velcro strap. Makes them visible at night during walks. I use the slower flash mode.

One does not work, one works but the light is so dim. In trying to unscrew the 4 tiny screws and pry open the battery cover to check the batteries, I cut myself under my fingernail and made my hand sore. Some of the screws wouldn't even come all the way out. Very tedious to replace batteries and not worth the trouble. I'm returning and getting something that's USB chargeable. The only good thing I can say is they included a tiny screwdriver.

These are awesome. I clip one on my dog's collar when I have to walk her in the dark. Using the strobe setting works best for me, but any setting works well. The lights are bright and easy to use. They function exactly as I hoped they would. Happy customer here.

Both came with dead batteries and a loose clip. No hook for caribiner use either. Just a flimsy clip
