Problem Statement

Running at night is unappealing and dangerous because of the limitations of portable lighting.

Need for New Device

"I don't run at night because I don't like to deal with headlamps. If there were a more comfortable or better piece of equipment, I would run at night more."
—Kristen (Dartmouth student)

Limitations of current state-of-the-art portable lights include

  • Light beams bounce and cause disorientation and dizziness
  • Headlamps are uncomfortable
  • Lamps afford little peripheral vision
  • Breath can fog up a headlamp's beam

Solution

A lighting device mounted on a foam-padded Cordura belt with a mesh interior enclosing 13 LEDs on a circuit board mounted in foam core, a water-tight battery pack, and a safety light.
