In both cases the car driver mentioned they were unaware the cyclist was turning despite their hand signalling. No matter how the factors are analyzed, just shy of 40% of fatal bike accidents occur when the sun is down (in Toronto, Canada). Having a signal light both increases visibility and road confidence when it matters. Having a pocket-sized unit, which pairs with any wearable watch, allows you to keep the light close and ensure it's never lost. With funding, SIX will support many wearable devices; come with a gesture-recognition clip that sits on the seam of a jacket or shirt; and promises to notify when there's low battery, or when it falls out of range (or perhaps off of a bike).
