Fortified Bike's founders have a serious problem with bike light thieves. So much so that they created custom bolts that lock the Afterburner Anti Theft Rear Light to your frame for life. Fortified is so confident in this system that every light it produces also has a lifetime theft warranty. If it's stolen, it'll be replaced, so you never have to worry about taking your light off again. The Afterburner keeps you visible to motorists with a bright red, 30 lumen beam. Lock this lightweight aluminum attention grabber onto your seatpost, and it'll keep you seen in the dark for up to 24 hours. If you somehow find yourself in the dark for more than 24 hours, the batteries can be removed and recharged on the go in any USB port.
