Lighting Products and Fixtures Design Solarpill Emergency Location Marking by Alican Faydalı Solarpill is a solar powered lighting module designed to mark locations in emergency situations. The design offers two modes. The flashing mode gives a periodic signal for visual communication, and the second mode provides general lighting. Each module can be pinned to a tree or another suitable surface with a grooved steel needle, placed on the ground or hung. An integrated light sensor activates the light only when the surroundings are dark. The modules recharge in sunlight and work in cycles of 24, 48 or 72 hours.
