Pop r Rear - Leopard Whats loved by some, might not be so loved by others. So instead of compromising, knog has made 10x designs for three lights. Some are mild. Some are wild! But the striking form does not outshine the excellent function. Super bright, AA battery-powered, long runtimes, replaceable straps, and side illumination. So whoever you are, find your POP! LEDS- 1x Super-bright SMT LED designed to provide maximum brightness for duration of run time. SIDE ILLUMINATION- Giving riders 180 visibility BIKE ATTACHMENT- Tool-less attachment for handlebars and frames of 22-32mm diameter. LOW BATTERY INDICATOR- A red LED will shine from the front of the light when the batteries are low. This LED will remain on for 5 seconds after the light is switched off to indicate that batteries need changing. BUTTON- Longer button push on (0.75sec) prevents accidental turn on. Short presses switch modes continuously.
