An omni-directional airport taxiway light source comprising housing with a lower casing, an upper casing mounted to the lower casing, and an outer lens mounted to an opening of the upper casing. Upper casing provides a substantially flat upper surface. First sealing is mounted between the lower and upper casings. Second sealing is mounted between the upper casing and the outer lens. Light emitting diode is positioned in the housing below the outer lens so that light of the diode is emitted in the direction of the outer lens. Inner lens is located in the housing between the light emitting diode and the outer lens. A flat carrier for the light emitting diode is positioned in the housing and is mounted to the upper casing. The light emitting diode is mounted to the carrier.
