Niterider's Stinger Taillight gets bright without breaking your wallet. There's a reason this style of light has been so popular since Knog first introduced the Frog a few years ago, and that reason is convenience! The Lightning Bug is small, powerful, and easy to use. Wrap the strap around your bikes seatpost, turn it on and start pedaling. The subtle V-notch cut into the back of the Stinger fits onto the trailing edge of aero seatposts, allowing the Stinger to fit on your TT bike if you are late for work.
