Heh, I was thinking of something like a cross between an SDU-5/E distress strobe and a PASS device (those chirping locator things firemen use in case they get lost/disabled). Then every 15 seconds or so you'd get a brief chirp with a slightly delayed flash (chirp first to get you looking in the right direction to see the flash, specially at distance since the flash would reach you before the sound if you're far enough).
