What sequence can signal S.O.S. when in destress?

The sequence that signals S.O.S. in distress is a series of three short signals, three long signals, and three short signals again (· · · — — — · · · in Morse Code). This can be transmitted using sound, light, or visual signals. For example, using a flashlight, you would flash three short bursts, followed by three long bursts, and then three short bursts again. This universally recognized distress signal conveys the need for urgent assistance.
