The Knog Plus Twinpack Light Combo includes a head light and tail light that are not only impressively light and substantially bright, but are easily mounted to bicycle handlebars, forks, seatposts, seatstays, or pannier racks using convenient quick-release magnetic mounts. You can even remove the magnetic mounts and hook the lights to your backpack or shirt with the integrated clips. Perfect for commuting, road cycling, or even running, these versatile little lights are highly water-resistant and feature a 40-lumen output on up front paired with 20-lumens for the tail light. The bright LED bulbs shine with five different modes that improve safety by alerting other road users to your presence. Choose between two different flash modes, strobe, pulse, or a steady beam mode depending on your preference and the conditions at hand. Both lights are rechargeable, and plug directly into a USB port to charge with no cable required.
