I have a friend that goes biking all the time. She bikes every weekend and two or three times during the week before school. Sometimes it's still dark out when she gets out to bike. I always worry about her getting hit by a car. I really want her to get a jacket like this.
This jacket is called the Sporty Supahero cycling jacket. It has LED lights built in that change if the biker is stopping or turning. The jacket includes 64 RGB LEDs incorporated into flexible, wearable circuit boards, an acceleration sensor, and a gyroscope. The sensors detect the motion of the biker. When braking the jacket glows read, and blink when turning.
