If you live in a city and take runs, walks, or rides at night you know how dangerous it can is. Cars are driving fast and drivers are more distracted than ever. Anything you can do to draw attention to yourself in the form of reflectors or LED lights is always a good call.
The Rumble Shoe Lights ($12.99) are lightweight and clip-on to all shoe sizes. They are lit via a battery (CR2032) that lasts for about 90 hours or use. There are 4 light modes; solid, flashing, sensor, and S.O.S. Great idea and a cheap investment in protecting you and your loved ones.
