Irene Posch posted these amazing Early Winter Night Biking Gloves...

"The Early Winter Night Biking Gloves consist of knitted wool gloves having conductive areas on each fingertip as well as on the palm of the hand. When forming a fist they close an electric circle, causing the LED-arrow at the back of the hand to light up. A 3V coin cell battery needed to power the LEDs is hidden in the cuff of the gloves."
