NightRunBlinker

Safety. Caution oncoming traffic with your flashing mobile phone or watch.

Are you also a runner ? I often run in the dark (morning or night) to meet training schedule mileage. Yeah, there are plenty excellent safety products with reflectors and/or emits caution blinking. But since I am already wearing my GPS/heart-rate-monitor watch and/or strapped to a phone, why not double their usefulness ?
