    Great product

    Always the nicest quality, I absolutely love the brand

    Rapid X Rear Bike Light

    The unit works perfectly as designed. It not only is highly visible from the rear, but from the side as well, which is significant. Battery life is good and you have the option of turning down the lumens to conserve power. Now, if CatEye will adapt some bear spray to the light so we can safely go offroad.... :o)
