An ultra compact, safety focused, rear light to help you get home no matter the time of day. Small enough to shove in your pocket for errand running, or keep always mounted to your bike, the Femto Drive USB is an ideal ride safety companion. Offering five output modes, one solid mode, a pulsing mode, and three flashing modes, with a maximum output of 5 lumens from the single LED emitter. The flashing patterns help other road users notice you from further away, and the molded lens offers a staggering 270 degrees of visibility using Lezyne's Wide Angle Optics optimization. The body of the light is constructed from co-molded Composite Matrix, and offers an impeccable IPX7 rating, meaning you can have the confidence to ride in the nastiest rain and know your taillight will keep shining bright the whole time. This light is USB rechargeable, offering up to 15 hours of battery life in any of its flashing modes, and 4.5 hours in its solid output mode. To charge the light, simply unscrew the back plate of the light and plug it in to a micro-USB cable and it'll be back to full charge in 2.5 hours.
