It doesn't hurt to use more lights when you're running at night – it could keep you safer. Put some light on your wrist, ankle, or arm with a simple slap-on bracelet (like the one you probably had as a kid) with LED illuminating functionality. Simply slap it to snap it and press the button to turn on the light. Press the button again if you want it to blink. It's perfect for playing night time frisbee with your friends.
