The characteristic of Chaumont Harbor light is defined by its signaling pattern, which indicates how it communicates to vessels. The designation "F G" stands for "fixed green," meaning that the light remains on continuously and emits a steady green illumination. This type of light is typically used to mark navigational channels and provide guidance to vessels, signaling safe passages and indicating the presence of hazards in the area.

The fixed characteristic is particularly important for mariners, as it allows them to easily recognize and rely on this light as a consistent reference point during their navigation. The color green further signifies port side markers in many navigational systems, indicating that vessels should keep this light to their left when traveling upstream or towards the port.

The other options detail different light characteristics, which involve flashing patterns or different colors (red and white), but these do not apply to Chaumont Harbor light, which has a fixed green illumination. This understanding of navigational light characteristics is crucial for safe travel on waterways like those surrounding Lake Ontario.
