KVS 3 LED Safety Clip on Lights for Running Biking Dogs Ultra Bright 2 Red and 1 White LED Safety Lights for All Outdoor Activities. Great Stocking Stuffer Guarantee

I ordered two of these. One came with two red lights and one white, as advertised, but the other came with two white lights and one red. I needed 4 red lights. 4 of the 6 were seriously dim, right out of the case. Replacing the batteries requires removing the back, which requires removing 4 almost microscopic screws, 2 of which fell into the carpet, never to be seen again. The lights were reasonably bright after.Replacing the batteries with the spares.which came with. Unfortunately, these spares did not even last an hour before they, too, became quite dim. On top of all of this, when I went to remove them after my evening run, the clip for one of the red lights broke apart in my hands.They are cheap. For a reason.

UPDATE -----2/3 of these lights broke after almost no usage whatsover. You get what you pay for. Except. In this case, you get basically nothing. Stay away------ END OF UPDATEOne dropped out of the box onto the floor in my garage - it has not worked since. The other... has a metal pin sticking out. I'll see if I can upload some pictures later. These things may appear to be reasonably priced... however, free would not be cheap enough for this garbage. SAVE YOUR MONEY.

I use these for walking my dog after dark. I clipped one to his harness and it stays perfectly in place. The three modes (always on, slow blink, fast blink) make them even more visible.

The white light didn't even work when it arrived and one of the red lights frequently shuts off spontaneously. I changed the batteries to no avail. Best price online but often dysfunctional. Would also like more white lights.

I bought 2 boxes of lights. Out of 6 lights, one didn't work right out the box. I even tried to changed the battery and it still didn't work. I like the white lights the best, as they are very, very bright.

These are really cheap, but not very water-resistant. I've had same issue on 2 of them on past runs - the strobe light quits and they just stay illuminated. Post run the lights will not shut off without removing the battery. I'll find a different brand next time that is slightly more suitable to long runs in the FL heat.

Works Great.

These are great lights. I use them for running in the early morning or evening. They clip easily onto my hat or jacket and I appreciate that they come with three light styles - solid, blinking fast, or blinking slow. They're a good investment!
