Neat idea but he's just getting started. 

At this year’s Interbike, that find was Lumenus, a small startup with one main product: LED-equipped jackets that interface with Google Maps on your phone to offer turn-signal indications for your chosen route and, crucially, added visibility, and automatic turn and brake signaling to other road users. 

Although only in prototype phase, the Lumenus products were some of the most memorable from the show. But what caught our eye wasn’t a jacket that tells you where to turn or even automatically signals those turns to other road users. It was the potential for what might come next. We caught up briefly with 23-year-old Jeremy Wall, founder of Lumenus, for his thoughts on what the future of wearables might hold. Hint: it’s not the Apple Watch.
