• Sayid used a makeshift flare from a firework to signal to Shannon and Kate to turn on the transceivers. ("The Moth")
• One was seen on the second raft and used to get the attention of another water-borne object, which turned out to be the others. ("Exodus, Part 2")
• One was seen with Naomi, which Hurley fired into the air, possibly alerting Mikhail of their location. ("Catch-22")  ("D.O.C.")
• Frank Lapidus used a flare to alert the other members of his team to his location. ("Confirmed Dead")
