The Defender is a theft-resistant, tough, waterproof handlebar-mounted bicycle light
People who commute by bicycle don't have to remove their pedals, racks or fenders when they park in public ... so why should their lights be any different? Well, because most battery-operated bike lights come off with the simple flick of a quick-release, or the turning of a single bolt. Massachusetts-based Gotham Bicycle Defense Industries, however, is attempting to address that problem with its Defender bike light. Not only is it theft-resistant, but it's also waterproof, and it looks like the light Dirty Harry would use - if he rode a bike.
