An LED light system applied in SEIL indicator backpack

An LED light system which was created by Lee Myung Su Design Lab, has been outfitted on a SEIL backpack to avoid traffic accident in night.

The system works through a wireless controller that clips on to the handlebars. The rider can flick a switch to say they intend to turn and which way. The backpack also outputs a flashing stop sign when the bike stops, and displays a range of different shapes and messages as you ride.
