The take-off and landing signal light is an integral part of the ship’s helicopter surface-assisted lighting system and light attenuation under special weather conditions are different. In this paper, the light color performance of an actual take-off and landing signal light are tested and the transmission characteristics under special weather conditions are analyzed. The methods of increasing the forward current and turn on the standby light source are studied. In this paper, the mathematical relationship between increasing current and increasing transmission distance is studied. The calculation of the example shows that the variation of the transmission distance of the take-off and landing signal by changing current is effective to adapt to weather conditions. For an example, the transmission distance of the given lamp is increased about 300 meters when the current is increased from 350 mA to 400 mA in sunny weather.
