SAS;
If it was me for real, my concentration would be on the get down bit. If the weather is overcast at 200' then frankly that is our national minima, and lights will be visible at 200' if it is overcast. A call to ATC to let them know by the PM what is happening and then sheer bloody concentration to keep the needles crossed I believe are more required than hands and eyes checking the right lever is being pulled. I would never criticise a pilot for continuing. Here in EASA land the visual clues required at DA are "elements of the approach lighting system" As someone once told me each light in an approach lighting system has two elements, therefore at DA if I can see one light I can see elements......................
