When must dayshapes be shown?

Explanation:
Day shapes are the daytime signaling method used to convey a vessel’s status. They are required to be shown only when there is daylight, serving as the daylight counterpart to navigation lights. Once it becomes dark, the signals switch to lights instead of shapes. So the timing factor is the daylit period, not fog, nighttime, or location such as open seas.
