A MINIATURE FLASHING LIGHT FOR BUOYS.

Abstract

A transistorized flashing light has been developed for use with small spar buoys. The light weighs two ounces, exclusive of the seven-cell mercury battery pack which acts as a buoy counterweight, and is visible at one mile to the unaided eye. The flashing circuit permits operation only at night. Battery life is approximately three weeks at a flash rate of 110 flashes each minute. Cost of the complete light in a watertight container is about twentyfive dollars. The miniature light is considered satisfactory under good visibility conditions for use with buoys spaced up to 2000 yards apart, and is recommended for use in mine countermeasures operations.
