I got these Super Bright Rim Lights in exchange for an honest review. These LED lights are pretty awesome. My boys love them! When you order you get to choose what color you want or you can choose multi colored. They send the batteries with them, so you don’t have to go buy them. They are designed to withstand the roughness that boys and kids put upon their bikes. They are waterproof, which is good because you know that kids love to go through mud puddles! They fit most all bikes and as an added bonus they provide better visibility to see my oldest when he is riding his bike at dusk or when it is dark. You can find them here.
