It can be argued that one of the crowning achievements of the Modern Age was bringing light from the darkness. However, that celebration was so the Industrial Revolution. Nowadays, we have 'robots' to perform our illuminating demands, and as cyclists, we now have the Portland Design Works Fenderbot Tail Light. Virtually theft-proof and impossible to miss on the road, the Fenderbot will keep you safe on your commute.Portland Design Works' Fenderbot Tail Light lives up to the image that its name conjures. Like a sentient, robotic bodyguard against inattentive drivers, the Fenderbot bolts to your commuter to grant safe passage through the night. At the heart of the system is a blindingly, strong red LED and a built-in precision reflector. The reflector jams a death-ray sized beam of pure light out to the eyes of distracted drivers, and even better, it meets the EU standards of visibility (seen over 500 feet away). The LED operates on one steady setting, and is powered by two AAA batteries.The Fenderbot attaches to your fender via a two-bolt system. And while your fender most likely doesn't have two ideally placed holes that are exactly 20mm apart, PDW incorporated this attachment design to eliminate theft. They recommend getting your 'DIY' on and drilling two 5mm holes at a 20mm distance between them. After this, it's smooth sailing for a lifetime of illumination. The Portland Design Works Fenderbot Tail Light is available in a 53x38x78mm size. The light also includes two AAA batteries, and weighs in around 62g.
