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.
