Every vessel, except hand-propelled vessels when on whitewater, in all weather from sunset to sunrise shall carry and exhibit the lights required in this regulation when underway or moored in other than a designated mooring area. During such times, no other lights shall be exhibited, except such lights as cannot be mistaken for the lights specified in these regulations or do not impair their visibility or distinctive character, or interfere with the keeping of a proper lookout.2. All vessels complying with the lighting requirements of the International Regulations for Preventing Collisions at Sea, 1972, or the Inland Navigational Rules Act of 1980 are considered in compliance with these regulations.3.

Every vessel less than 20 meters (65' 8") in length must display one all-round white light when at anchor.5. Flashing red or blue lights are prohibited on all vessels, except emergency or law enforcement vessels of the United States operating within federal authority, or of the State and its political subdivisions.6. Terms used: a. "Masthead light" means a white light placed over the fore and aft centerline of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on either side of the vessel, except that on a vessel of less than 12 meters (39' 5") in length the masthead light shall be placed as nearly as practicable to the fore and aft centerline of the vessel.b. "Sidelights" means a green light on the starboard side and a red light on the port side each showing an unbroken light over an arc of the horizon of 112.5 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on its respective side. On a vessel less than 20 meters (65' 8") in length the side lights may be combined in one lantern carried on the fore and aft centerline of the vessel, except that on a vessel of less than 12 meters (39' 5") in length the sidelights when combined in one lantern shall be placed as nearly as practicable to the fore and aft centerline of the vessel.c.

In a sailing vessel of less than 20 meters (65' 8") in length the lights prescribed in paragraph a. of this regulation may be combined in one lantern carried at or near the top of the mast where it can best be seen.c. A sailing vessel underway may, in addition to the lights prescribed in paragraph a. of this regulation, exhibit at or near the top of the mast, where they can best be seen, two all-round lights in a vertical line, the upper being red and the lower green, but these lights shall not be exhibited in conjunction with the combined lantern permitted by paragraph b. of this regulation.d.(1) A sailing vessel of less than 7 meters (22' 9") in length shall, if practicable, exhibit the lights prescribed in paragraph a. or b. of this regulation, but if not, the operator shall have ready at hand a flashlight or lighted lantern showing a white light which shall be exhibited in sufficient time to prevent collision.(2) A vessel under oars may exhibit the lights prescribed in this regulation for sailing vessels, but if not, the operator shall have ready at hand a flashlight or lighted lantern showing a white light which shall be exhibited in sufficient time to prevent collision.37 CR 19, October 10, 2014, effective 11/1/201438 CR 07, April 10, 2015, effective 5/1/201539 CR 03, February 10, 2016, effective 3/1/201639 CR 07, April 10, 2016, effective 5/1/2016
