Which light is characterized as yellow and has the same attributes as a sternlight?

The towing light is characterized as a yellow light and is used to indicate that a vessel is engaged in towing operations. Its function and attributes are specifically defined under the COLREGs, aligning it closely with a sternlight, which also has a fixed and visible light at the stern of a vessel. Both lights serve the purpose of indicating the presence and type of activity of the vessels, allowing for safe navigation and collision avoidance.

While the masthead light is used on power-driven vessels and is white, the special flashing light serves a different purpose related to vessels engaged in certain activities and typically appears as a yellow or red light but does not maintain the same function as a sternlight. The starboard light, also white, indicates the side of the vessel and is not associated with towing or the specific operational context of a sternlight.

Understanding these attributes emphasizes how the towing light signifies additional duties and responsibilities of the vessel, thereby ensuring higher awareness for other vessels in the vicinity.
