§ 487.04  Lights for Watercraft
   All watercraft subject to this Water Traffic Code shall, in all weather from sunset to sunrise and at any other time there is not sufficient natural light to render discernible other watercraft and substantial objects on the water at a distance of three hundred (300) feet, carry and exhibit the following lights when under way. During such time no other lights which may be mistaken for those prescribed shall be exhibited.
   (a)   All Class A and one (1) powercraft shall carry the following lights:
      (1)   A bright white light aft to show all around the horizon; and
      (2)   A combined lantern in the forepart of the vessel and lower than the white light aft, showing green to starboard and red to port, so fixed as to throw the light from right ahead to twenty-two and one-half (22.5) degrees, two (2) points, abaft the beam on their respective sides. Each light thereby subtending an arc of one hundred twelve and one-half (112.5) degrees, ten (10) points, measured from the center line of the boat and beginning right ahead.
   (b)   All Class two (2) and three (3) powercraft shall carry the following lights:
      (1)   A bright white light in the forepart of the vessel as near the stern as practicable, so constructed as to show an unbroken light over an arc of the horizon of two hundred twenty-five (225) degrees, twenty (20) points, so fixed as to throw the light one hundred twelve and one-half (112.5) degrees, ten (10) points, on each side of the vessel; namely, from right ahead to twenty-two and one-half (22.5) degrees, two (2) points, abaft the beam on either side;
      (2)   A bright white light aft to show all around the horizon and higher than the white light forward; and
      (3)   On the starboard side a green light so constructed as to show an unbroken light over an arc of the horizon of one hundred twelve and one-half (112.5) degrees, ten (10) points, so fixed as to throw the light from ahead to twenty-two and one-half (22.5) degrees, two (2) points, abaft the beam on the starboard side. On the port side a red light so constructed as to show an unbroken light over an arc of the horizon of one hundred twelve and one-half (112.5) degrees, ten (10) points, so fixed as to throw the light from the right ahead to twenty-two and one-half (22.5) degrees, two (2) points, abaft the beam on the port side. The side lights shall be fitted with inboard screens of sufficient height so set as to prevent these lights from being seen across the bow.
   (c)   Sailboats propelled by machinery whether under sail or not, shall exhibit the same lights as prescribed for powercrafts of comparable length.
   (d)   Every sailboat, regardless of length, under sail alone shall exhibit:
      (1)   On the starboard side, a green light, so constructed as to throw an unbroken light over an arc of the horizon of one hundred twelve and one-half (112.5) degrees, ten (10) points, so fixed to throw the light from right ahead to twenty-two and one-half (22.5) degrees, two (2) points, abaft the beam on the starboard side;
      (2)   On the port side, a red light, so constructed to show an unbroken light over an arc of the horizon one hundred twelve and one-half (112.5) degrees, ten (10) points, so fixed to throw the light from right ahead to twenty-two and one-half (22.5) degrees, two (2) points, abaft the beam on the port side;
      (3)   At her stern a white light, so constructed that it shall show an unbroken light over an arc of the horizon one hundred thirty-five (135) degrees, twelve (12) points, so fixed as to show the light sixty-seven and one-half (67.5) degrees, six (6) points, from right aft on each side of the vessel, and of such a character as to be visible a distance of at least two (2) miles, and carried as nearly as practicable on the same level as the side lights, or, in lieu of the white stern light, a readily accessible lantern or flashlight showing a white light.
   (e)   Rowboats and canoes shall carry either a white light visible all around the horizon or a readily accessible lantern or flashlight showing a white light.
   (f)   All watercraft required to carry a readily accessible flashlight or lantern shall exhibit such flashlight or lantern in sufficient time to avert a collision.
   (g)   A white light visible all around the horizon shall be exhibited by watercraft while at anchor.
   (h)   Every white light prescribed by this section shall be of such character as to be visible at a distance of at least two (2) miles. Every colored light prescribed by this section shall be of such character as to be visible at a distance of at least one (1) mile.
   (i)   In lieu of the lights required by this section, any powercraft may carry and exhibit lights required by:
      (1)   “Act of February 8, 1895,” 28 Stat. 645, 33 U.S.C. 241, as amended;
      (2)   “Act of September 24, 1963,” 77 Stat. 194, 33 U.S.C. 1061, as amended;
      (3)   “Act of May 21, 1948,” 62 Stat. 250, 33 U.S.C. 301, as amended.
   (j)   In lieu of the lights required by this section, any sailboat may carry and exhibit the lights required by either:
      (1)   “Act of February 8, 1895,” 28 Stat. 645, 33 U.S.C. 241, as amended;
      (2)   “Act of May 21, 1948,” 62 Stat. 250, 33 U.S.C. 301, as amended.
