Nighttime bicycling is just not safe without a light. Yet, many riders either forget their lights at home or worse, have their lights stolen. The new Theft Proof Bike Light was designed by MIT engineers to stay on and keep you safe. Made of lightweight aluminum, it attaches to any standard handlebar in 30 seconds with a custom security screwdriver that can’t be purchased in any hardware store. One set of batteries provides superbright 50-lumen white light for 50 hours steady (or 100 hours flashing).
