Today I spoke with David Allen, of LRI and the father of Photon MicroLights. Apparently during the research and development phase of the Photon 3 an SOS signal flasher was considered. It was decided that this feature would not be incorporated into the new light. No plans currently exist to produce an SOS/Rescue Photon MicroLight. The Photon 3 should be just as effective for emergency signalling purposes if programmed to one of the flash/strobe modes. Sorry, but I guess it doesn't hurt to ask though.<br><br>
