The process is:
Some ace in management decides putting these lights on is a great idea.
A Flight standing order goes out to the troops telling them to do it because its "worlds best practice."
Many troops may disagree but their voices fall on deaf ears.
There is a belief in management that because you are selected to a managerial role you automatically become more intelligent than your fellow pilots, many of whom have been in aviation a lot longer, have much better skills, and have more knowledge than you will ever have. " Worlds best practice" is actually a phrase meaning "in my opinion." However managers opinion wins over line pilots opinion.
I suggest if this practice is causing problems complain to QF and submit safety reports via the available systems.
