Featuring a long-lasting LED module encased in specially formed housings, the TwistList is designed with a curved back that rests snugly against the round surfaces on your scooter or power chair. Grooves on each side hold sturdy, flexible rubber Gear Ties in place - with ends to wrap through, over, around, or under the front or the rear of your scooter or power chair of any size. Twist closed, and you're done. The bright, long-lasting, battery-powered LED is activated with a simple push of a button! Available in Red or White!
