Emplazamiento de luz de Obstáculos
Se coloca una o más luces en la parte superior de obstáculos. Si la parte superior del obstáculo se encuentra a más de cuarenta y cinco (45) metros sobre el nivel del terreno circundante, se colocarán luces adicionales a niveles intermedios.
The number and positioning of the lights at any level of the sorrounding terrain must be such so that the obstacle is indicated on all azimuths. The upper light or lights must be positioned so that it shows the border or upper point of the obstacle. If the obstale is to be a chimeney the lights must be positioned between 1,50 meters and 3.00 meters below the peak. In case the obstacles are of great exterior or very closely grouped, lights must be positioned at the most upper point relative to the signaling surface, at interval not greater than 45 meters so as to indicate it's general configuration and the size of the obstacle.
