Kate Hartman and Angela Mackey’s project Vega Edge (just funded on Kickstarter) is a versatile wearable light:
The Vega Edge is easy to use and versatile. Made with laser-cut leather, it snaps securely to your clothes using four strong magnets. It has a thin strip of retro-reflective fabric integrated into the design for added visibility. You can wear it discreetly by day or brightly at night on your coat, cardigan, hood, scarf, handbag, collar, pocket, belt, or wherever you’d like a touch of light.
