I received a set of the original Knuckle Lights for Christmas for running after dark. So far I've only used them for walking my dog at night. They are so much easier than carrying a flashlight with the dog and brighter too. However, one of the lights suddenly stopped working shortly after I received them. After a quick chat with the Knuckle Lights people, I received a new set to replace the defective light within a couple of days. They only required a photo of the light in question, so I didn't have to return it. Very happy.

I have tried a variety of hand held running lights and these are the best yet. The lights can be used together or in different directions. My hands are still free to use when I need them.

I love love these! They’re so much brighter than ones I’ve had in the past, and I love that they’re rechargeable!

I’m an early morning runner. I live in an established neighborhood with mature trees. The root system of the trees often grows under the sidewalks and pushed up the surface creating numerous trip hazards which I’ve experienced. With the knuckle lights, I’m able to see the surface right in front of me and what up ahead or to my right or left. I had been using a headlamp for years and that requires me to keep my head down to see to sidewalk which creates an awkward running form. Knuckle lights are the way to go.

Gave these to my fiance for Christmas because he always runs in the dark. He's used them a few times now and he absolutely loves them. Says they are super comfortable and the light is super bright. Makes me feel a lot better knowing that he is safer out there!

As advertised, they are brighter than the battery powered model. I've had the battery model for a couple of years and am glad to have the rechargeable version. Since most of my nighttime running is in the cold winter months, regular batteries don't last very long. These seem slightly heavier, but are easier to adjust. Good product.
