This was a concept for a bag that is both useful from a safety standpoint, environmentally friendly, and is cool to look at.

It incorporate an EL wire, rechargeable batteries, and a solar panel. The inclusion of solar panels ensure that the EL panels will remain charged during the day, cutting down in batteries and increasing convenience (especially if usb charger is included).

Prototype bag was constructed from a potential source, but build quality was poor. Regardless, design principle remains workable. However execution could be improved.
