the ‘seil bag’ by korean leemyungsu design lab is a backpack for bicycle riders with a clever safety feature — illuminating LED lights on its exterior fabric indicate traffic signals such as left and right arrows to auto drivers behind. basic signs, like ‘stop’, ‘sorry’, and emergency markings illustrate a programmed message to vehicles at the rear of the cyclist. the bike rider can control the various information they want to deliver through a simple, detachable wireless controller fitted to their handlebars. the flexible LED display hidden within the fabric can be applied to either the backpack, or a pouch and can be self-programed to relay symbols, emblems, and badges through a smartphone app. seil bag is a piece of wearable IT that integrates style and technology, while protecting urban bikers from vehicular accidents. the project is currently seeking funding through kickstarter, here.
