I created a light sensing LED light up running tank top intended for running and training or biking at night. The light sensor is embedded into a pocket of the tank top at the base of the back of the neck. The light sensor is sewn up so that the light is always on when the lilypad is turned on.

If I had more time, I would have liked to have made the LED embedded within a pair of running leggings. For this timeline, it was more logical to embed the LEDs into a running shirt for easier and faster construction capabilities.
