The Plugger Twinpack is perfect as an every-day light set. Inspired by Knog's roots, it comes in overmolded soft touch TPU (rubber-like material) and includes a powerful 350-lumen front light paired with a 10-lumen rear light. This light set is packed with innovative touches such as a low battery indicator and cut-outs in the front light body for improved side visibility. Plus, like all Knog bike lights, both the front and rear lights are fully USB rechargeable. Designed to work with all genres of bicycles from commuters to road bikes, each light in the set also comes with two different size silicone bands for securing it to handlebars, seat stays, and seatposts. Increased Side Visibility Cut-outs in the side of the Plugger design result in improved side visibility. Given the fact that 78% of accidents happen with cars not seeing bikes at intersections, any additional visibility from the side is a good thing. USB Rechargeable As with all of Knog's bike lights, the Plugger is 100% rechargeable. Recharging is achieved with the micro USB port conveniently located behind the large rear button. Using a micro USB cable (not supplied) you can then simply recharge off any USB port. Easy One Button Operation A large, soft-touch button ensures easy operation of the Plugger. The oversize button allows the user to turn the light on and off with ease, even when wearing gloves. Low Battery Indicator Don't be caught out with an uncharged bike light again. With the Plugger's clever side visibility window doubling up as low battery indicator, you'll know when exactly when your light needs recharging.
