Under Inland Navigation Rules, any high-intensity white light flashing at regular intervals from 50 to 70 times per minute is considered a distress signal. Such devices do NOT count toward meeting the Visual Distress Signal requirement, however.

Check the label to see how long each device will remain illuminated, then choose one best suited to the conditions in the area where your vessel is typically used. Store in a cool, dry place. A watertight container painted red or orange and prominently marked "DISTRESS SIGNALS" or FLARES" is recommended.
