In the U.S. Aids to Navigation System, what type of lights will lateral aids display when entering from downstream?

In the U.S. Aids to Navigation System, lateral aids are designed to help boat operators determine their position relative to navigable waters, particularly in channels. These aids are categorized based on their color and the nature of their light characteristics, which indicate whether a vessel should keep to the right or left side of the channel when entering from downstream.

When entering from downstream, lateral aids may display lights that are flashing, occulting, or quick flashing. Flashing lights emit a series of flashes at regular intervals, while occulting lights are lit continuously for a specific duration followed by a short period of darkness. Quick flashing lights produce a rapid sequence of flashes. Since any of these types of lights could be used to signify the side of the channel, the correct answer acknowledges the range of light characteristics possible for lateral aids. Therefore, it is accurate to say that any of the described light types could be displayed, as they all serve the purpose of providing critical navigational information to operators as they approach the channel.
