So many ways to use them
I gave these 5 out of 5 stars
This set of 2 LED safety lights come with a clip Velcro strap. They can be clipped onto clothing, strapped onto an arm or leg, put on a bike or even hooked onto a dog collar. They are for runners and bikers so they are visible in the dark or low light. I am not a runner and currently not a biker but these lights are very handy for going on walks or putting them on my son when he goes trick or treating at Halloween. Even while wearing an all black costume, kids can be seen in the dark thanks to these lights. The lights can flash or they can stay on. They come with batteries already installed and there are extra batteries included. They are 2 inches long. I received this item for free to try in exchange for my honest and unbiased review.
