What Our Gearhead(R) Experts Are Saying: "This is the kind of light I throw on every bike-simple, bright, and reliable. The AA battery power means I never have to worry about charging, and the side visibility really boosts safety in traffic. Plus, the fun designs add some personality to the ride."We like to keep things simple when it comes to safety, and the Knog Pop r Rear Light makes it easy to stay visible without adding bulk or hassle. With its playful Brain design, this light brings personality to our bike while delivering the performance we need for everyday riding. Visible from over three-quarters of a mile away, the Pop r uses a super-bright LED that shines consistently throughout its runtime. Side illumination expands visibility to 180 degrees, making us more noticeable to cars and other riders. Powered by an included AA battery, it runs long, signals when power is low, and is quick to swap out when needed. The tool-free strap mount fits most seatposts, and the light rotates 90 degrees so we can fine-tune placement. For commuting, evening rides, or just a touch of extra style, this little light keeps us rolling confidently.
