Is the strobe light considered as an effective distress signal at all times?

The strobe light is not considered an effective distress signal at all times because its visibility and interpretability depend on various environmental conditions. While a strobe light is particularly useful and effective in low visibility situations, such as at night or in fog, there are conditions where it may not serve as a clear distress signal.

During the day, for instance, the bright sunlight can diminish the visibility of the strobe light, making it hard for others to see and recognize it as a distress signal. Additionally, a strobe light may not be as easily distinguishable from other bright lights in urban settings or busy waterways, potentially causing confusion rather than conveying the intended message of distress.

Consequently, while the strobe light has its advantages as a distress signal, it is not consistently effective and should be used in conjunction with other signals or methods to ensure that a distress situation is communicated clearly. Therefore, option B accurately reflects the limitations of the strobe light in various conditions.
