Knog Blinder 4 GT (Rear)

Knog's Blinder 4 light series packs a huge amount of light into a tiny package. A red stripe pattern alerts people to your presence so you'll be seen while riding in the dark. The optics are arranged to direct light in a powerful beam, while the waterproof body attaches to seatposts and handlebars with ease. A USB port allows for convenient recharging and tactile buttons make for easy operation, even while wearing gloves.
