ABSTRACT:
The indicator light is constituted by a panel supporting juxtaposed and alternating neon tubes of blue, yellow, green and red color, these colors being assigned to the cardinal points north, east, south and west respectively. These tubes have voltage applied by means of a selector controlled by a weather vane, activating permanently the neon tubes of the color corresponding to the position of the weather vane. A series of colored lamps, displaying the Beaufort scale, indicates the wind velocity by means of a selector controlled by the anemometer. Colored light sources indicate the air pollution level.
