Non-Pyrotechnic Visual Distress Signals
The electric distress light is accepted for night use only and must flash the international SOS distress signal automatically.
The distress flag is a day signal only. It must be at least 3 x 3 feet with a black square and ball on an orange background.
Although this signal does not meet VDS equipment requirements, wave your arms to summon help if you do not have other distress signals on board.
