Knog Plus Twinpack Black
With a runtime of up to 20 hours with the Eco Flash mode, these mountable on bike or person lights will make sure you are seen by other cyclists and hikers alike. Outputting 40 lumens of light at the front, and 20 to the side, this rectangular yellow and red light combo is USB rechargeable, and completely waterproof, allowing you to be seen by other people in the dark as well as in the rain. With its smart clips, you can mount the lights onto your handlebars, or other parts of your bike, and even clip them to your clothes. The Knog Plus Twinpack gives a five dollar savings if you need two lights.
