Light Weave

Light Weave is a type of flexible LED-based fabric capable of emiting light when powered. 
In the often dark and shadow-filled streets of the cities, having a garment that literally produces its own light is one way for the Bright citizens to stand out amongst the crowd when they're out on the town at night. 
Whether the Light Weave is used to provide accent to the garment (aka. light ribbon) or to provide illumination to see (within a hood or umbrella), the technology would require some sort of flexible wiring throughout the garment and a power-storage device.
