Additional lights should be equally spaced along the cable's overall length for each 350 feet (105m) or fraction thereof.
b. Light Distribution. The intensity of each light should be approxi- mately 1,000, and preferably 1,500, effective candelas at every point in the horizontal plane (and a minimum of two degrees in the vertical plane) with a flash rate of 40 pulses per minute.

23. LIGHT CONTROL DEVICE. The operation of each light may be controlled by a photocell controller which automatically turns the light on when the north illumination on a vertical surface drops to 60 footcandles but before reaching 30 footcandles. The reverse order should apply in transitioning from nighttime to daytime operation.
24. OTHER FEDERAL OR LOCAL COVERNMENT REGULATIONS. Rules and regulations as prescribed by the FAA and other Federal and local government agencies pertaining to the use of balloons, kites and associated equipment in the navigable airspace are not affected and shall apply.
