Nighttime urban bike adventures call for functional lighting that won't get in the way or crimp your style. The Knog Blinder Mob Four Eyes Front Light serves as a bright beacon wrapped in a sleek little package. It nests unobtrusively on your handlebars but kicks out 80 lumens of light for over 1,000 meters of visibility. The body of the Mob Four Eyes is made from UV resistant industrial grade silicone and polycarbonate housing, providing a waterproof and durable casing that will shepherd this light through all the inclement weather you might encounter on your cycling adventures. The lumens are delivered by four Surface Mount SMT LEDs, built to throw out maximum light for up to 90% of the battery run time in each mode. The Mob Four Eyes is powered by a rechargeable Lithium Polymer battery with an integrated, weather resistant USB plug. The battery's run times range from five hours in steadylow mode to 76 hours in eco flash mode. With a total of five different modes to choose from, you can customize the brightness with a quick button click to meet your riding needs on the fly. The Knog Blinder Mob Four Eyes Front Light uses a silicon strap to attach to handlebars ranging from 22 to 32mm in diameter. It comes complete with two removable silicone straps, one for 22 27mm bars and the other for 27 32mm bars.
