It is probable that this device was used by landing parties in "The Galileo Seven", since communications was not possible, and one party beamed aboard after they signaled using one, when the creatures attacked. Communications with the shuttlecraft Columbus might have used a modulated laser signal with a set of codes for a limited set of pre-determined messages. Possibly as a result of the incidents in this episode, the beacon might become standard equipment aboard a shuttlecraft.
