Which is correct regarding a "special flashing light"?

A special flashing light is an important visual signal used on vessels to convey specific information about their operation. This signal is particularly relevant for vessels that are engaged in certain activities, such as towing, operating under restricted visibility, or being temporarily out of service.

When considering the function and requirements of a special flashing light, it indeed operates under specific rules outlined in maritime regulations. Such lights are not restricted to nighttime use; they can be utilized during the day as well to enhance visibility to other vessels. This allows for improved communication and safety on the water.

The notion that a special flashing light must be operated continuously relates to the need for consistent signaling to indicate the presence and status of a vessel to nearby operators. This continuous operation reinforces the message being conveyed and helps to prevent potential accidents or misunderstandings.

Moreover, while the special flashing light might indicate a vessel is under tow, it is not exclusively designated for that purpose. Instead, it serves various functions in signaling to other vessels what specific activities the vessel is involved in, enhancing navigational safety.

Thus, the option stating "all of the answers" consolidates these important aspects about the special flashing light into a single, comprehensive statement reflecting its varied uses and the operational requirements involved.
