What does an alternating red and yellow light indicate?

An alternating red and yellow light serves as an important signal indicating government activity. This type of light is often utilized to alert mariners and other waterway users of the presence of governmental operations, which could include the activities of agencies such as law enforcement or environmental protection efforts. The alternating colors are particularly effective in drawing attention and ensuring that the signal is recognized from a distance, as they stand out in various weather and lighting conditions.

In the context of navigation and safety on the water, understanding the significance of such signals is crucial. Government activity may range from patrols, inspections, to even search and rescue operations, and the alternating red and yellow light serves as an important alert to remain cautious and observant in those areas.
