There are few things more frustrating than walking out to your bike after an evening with friends or a long study session to find your light stolen. Foil those light thieves with the Fortified Bicycle Defender Anti Theft Bike Headlight. It's built to deter theft and stick around to guide you home safely with 50 lumens of bright light. The light's anti theft properties come courtesy of Fortified's signature security bolt, which locks the light to your handlebars with a unique bolt head for theft proof mounting. If the light does happen to get stolen by a particularly dedicated thief, the Defender comes with a lifetime warranty for theft so you can get a new light and get back on the road quickly. The body of the Defender is made of lightweight aluminum for a water and shockproof casing that will survive inclement weather and any run ins with errant branches along your route. The light itself is powered by three batteries with claimed run times ranging from 50 hours in steady mode to 100 hours in flashing mode.
