No person may:
(a)During the period from sunset to sunrise (or, in Alaska, during the period a prominent unlighted object cannot be seen from a distance of 3 statute miles or the sun is more than 6 degrees below the horizon)—
(1)Operate an aircraft unless it has lighted position lights;
(2)Park or move an aircraft in, or in dangerous proximity to, a night flight operations area of an airport unless the aircraft—
(i)Is clearly illuminated;
(ii)Has lighted position lights; or
(iii)is in an area that is marked by obstruction lights;
(3)Anchor an aircraft unless the aircraft—
(i)Has lighted anchor lights; or
(ii)Is in an area where anchor lights are not required on vessels; or
(b)Operate an aircraft that is equipped with an anticollision light system, unless it has lighted anticollision lights. However, the anticollision lights need not be lighted when the pilot-in-command determines that, because of operating conditions, it would be in the interest of safety to turn the lights off.
