There are innumerable ways of staying visible on a bike ride or jog late at night, but none as unique or customizable as Fos. This 2mm-thin velcro-lined fabric patch sports an array of super-bright LEDs, each offering 64K shades of brightness, and displays customized messages, graphics, advertisements, turn signals (when using GPS navigation), calories burned, and more, using a Bluetooth-equipped iOS or Android device. Fos is also water-resistant for use in adverse weather, lasts roughly 4 hours per charge, comes in 3 sizes – standard (32 x 8), double height (32 x 16), or as a triple-width belt (96 x 8) – and can be used in conjunction with other Fos units to form one bigger composite display.
