Messenger bag LED matrix keeps bikers safe at night

The design is quite simple, there’s a large flap which is attached at the top of the bag and has a couple of clips at the bottom to keep ti closed.

The lights shine through the orange fabric, keeping them fairly safe from the weather and giving them a reddish hue.
