I purchased the lights because my wife is a runner. She often runs early in the mornings.
She loves them! She says the work great.

I bought two pair of the orange Knuckle Lights and had planned on keeping them myself til my co-workers shared about going walking with a friend after work. I had told her about the Knuckles before so I sold one pair to her. She made good use of them last night on their walk. I suspect that she may be in the market for more.

Though my daughter is not a runner her family has a new puppy. The knuckle lights allow them to see where they're going and hang on to the dog leash. Makes for a safer walk in the fall Darkness

I run in the morning when it’s still dark in winter and these really light my way and help me feel safe.

These lights are manufactured to hold up to all sorts of challenges, including a bear chewing on it! I forgot and left my knuckle lights in my pack outside my tent. A small black bear chewed the strap but the light survived. Knuckle lights customer service replaced the strap. Awesome!

These are my second pair of Knuckle Lights. I love them! They are lightweight and really bright! These are a great purchase!
