Conn. Agencies Regs. § 15-121-A18 - Public safety light
Vessels engaged in government sanctioned public safety activities, and commercial vessels performing similar functions, may display an alternately flashing red and yellow light signal. This identification light signal must be located so that it does not interfere with the visibility of the vessel's navigation lights. This identification light signal may be used only as an identification signal and conveys no special privilege to the vessel. Public safety activities include but are not limited to patrolling marine events or regattas; traffic control; salvage; firefighting; medical assistance; assisting disabled vessels; and search and rescue. The public safety light is not a towing light. The light fixture shall be a standard police type beacon, with clear, weatherproof lens over a pair of rotating lights; one red and the other yellow. The lights shall rotate between 70 and 100 revolutions per minute.
