In New York State, blue lights are generally allowed on police vessels only, signaling their authority and purpose on the water. These regulations can vary, so it is important to consult the latest maritime and local laws for accurate information.
Step-by-step explanation:
The question pertains to the special regulations concerning the lighting used on emergency vessels, specifically police vessels, in New York State. In general, the lighting on police and other emergency vessels is regulated to ensure visibility and the conveyance of their purpose. The use of certain colored lights is often reserved for these official boats to signal their status and function.

Blue lights remain a widely recognized symbol for police presence. In New York State, police vessels may be authorized to display blue lights when engaged in law enforcement activities to distinguish them from other vessels and signal their authority and purpose on the water.
It is important to note that these regulations can vary, and always referring to the latest maritime and local laws is essential for the accurate identification of lights permitted exclusively for police vessels.
