The Longest Lasting Super Bright Rim Lights are pretty neat! You can add them to any tire valve stem to create a unique personalized LED Colorful light experience. My daughter loves them on her bike, and thinks that she is super cool compared to the other kids in the neighborhood, because her tires light up, and there's do not! They come in 3 different colors and styles, plus there is a motion sensor, which can last for over 50,000 hours per the company's statistics. Please they were supper easy to install. Savannah had no problems installing these on her bike. Each package includes 2 green, 2 blue, and 2 colorful LED Valve Bike Lights, plus these are rust resistant and the company states that they are 100% waterproof and can be used in any terrain! This picture is actually from the company. I tried to take pictures, but they were blurry since the only time the lights come on is when her bike was in motion.
