I'm curious about this lose of night vision angle. Seeing as though you need about 30-45 of darkness (absolute darkness) to get night vision up to scratch your night vision is already ruined by the sea of lights that modern airports are. City lights in the back ground, landing lights of approaching aircraft, strobe lights of aircraft either on approach or crossing runways, the brightness of Rwy lights both CL and edge, the apron overhead lights, the headlights/flashing lights of ground vehicles, the light coming from the terminals. These all ruin night vision. Not too mention the fact you only turned down the cockpit lights when you are about to taxi and for the fact that you use white light in cockpits for reading airport charts etc. This is not to say that the wing lights are not annoying but to harp on about ruining night vision is a bit silly.
