Brass knuckles? How about Knuckle Lights? These Knuckle Lights are worn on your hands to light your path as your walk, jog or run. With 45 lumens per hand, extra wide flood beams and three levels of lighting (blinking, low, high), they’ll give off plenty of light so you can see, and be seen at night. And yes, they are weatherproof, lightweight and adjustable to your hands, so they’re comfortable to wear. Actually if you think about it, they’ll probably be more important to protecting you than brass knuckles. Comes in black, blue, pink and yellow.
