6. Every flying machine at anchor or moored on the surface of the water shall display lights in accordance with the following provisions of this paragraph:—
(a) in every case, it shall display forward centrally where it can best be seen, a white light visible all round the horizon at a distance of at least 1 mile:

(b) in addition, from the mooring cable of the balloon or kite there shall be displayed, at intervals of 1,000 feet measured from the said group of two lights, similer groups of two lights, white and red, and, if the lowest group of lights is obscured by clouds, an additional group shall be displayed below the cloud base:
(c) in addition, the position of the object to which the balloon or kite is moored on the ground shall be marked by a group of three flashing lights arranged in a horizontal plane at the apexes of a triangle approximately equilateral and each side of which measures at least 80 feet; the side of this triangle, perpendicular
