The Colorful Wheel Rim Lights are really cool. The package states they are for car wheels but there is an adapter that makes them work on bike tires - well really any tire with an air valve. With six in the package you can use them on one car and a bike, or three bikes. The Wheel Rim Lights pictured above and in the video below are the colorful valves. My daughters were excited to place them on their bikes. My younger daughter took the multi colored ones and my older daughter chose the blue lights. The lights light up when the bike moves, the lights last a little bit after stopping the bike but then go off soon afterwards. There are no switches or batteries to deal with.
