IIRC the Shawbury/CFS teaching of low level checks has changed a number of times since Bertie's time.
I stand by to be corrected but I believe it is now HOVL -
Height - including authorised minima and radalt bug setting
Obstructions - including lookout and crew arcs of responsibility
Visors - Down
Landing Lamp - on
I have to also agree with SS that I do not remember being told that the landing light was part of the checks as a bird deterrent rather than for conspicuity for other low flying aircraft - makes sense though.
