A 37575
is one of few talking sense here.
Manipulation with Landing Lights may make you more visible for any
opposite traffic, (how much of that will you have on ILS ?? ).
It is not ONLY opposite traffic that may cause a collision.
on the ILS became the norm in the UK during the 1970s.
I was told that this was to aid conspicuity and also acted as a deterrent to birds flying near the aircraft
For "conspicuity" it may be necessary only for the guy on TWR to identify you and give you "Cleared to Land", while some "wise guys" here would wait for "Cleared to Land" to switch the lights ON ??
as for deterrent to birds strike, it must have been invented by pilots too, birds do not need your lights to see you. They may be even confused by them...
