Under IMO Display standards, daylight visibility must be to at least how many observers?

Daylight visibility under IMO Display standards is about making sure signals are perceptible by more than one person. The requirement that daylight visibility be to at least two observers ensures redundancy so a signal isn’t misread or missed if glare, line-of-sight issues, or a single observer’s limited view interferes with perception. Having two or more observers confirms the signal’s presence and clarity from multiple angles, which enhances safety at sea.
