I often wonder how these pilots are not distracted when flying through cloud with landing light reflections in their eyes. Certainly their night vision must be seriously compromised - or is that not a safety factor anymore?
No amount of landing lights nor strobes have ever bothered me at night and/or in cloud. I realise it may do for others though so I turned them off if requested.
In the last couple of airlines it was SOP to have the landing lights on below 10,000'. I also turned on the second set of landing lights on the 747 when we received landing clearance on approach and when receiving takeoff clearance, etc.
