The SEIL bag is a backpack that you wear while you are bicycling and will let you send messages through a display on the back so that you can signal your right or left turns via an arrow, tell the person behind your to stop, send a thank you message to someone who stopped for you, or even display custom messages that you make beforehand.

The SEIL (Safe Enjoy Interact Light) bag comes with a device that you can attach right to your bicycle to send the messages to your backpack without your hands leaving your bike handles.
