Green guard:--- What are you smoking in India?????? For goodness sake please learn to write clearly so others may understand you.
Landing lights DO HELP the Birds to see and avoid the Aircraft, they have a much better chance of avoiding you at the last second via a quick manoeuvre than you do of them!!!
Besides there are other safety related reasons for using Landing Lights.
So until someone like NASA can positively confirm that Landing Lights make no difference I will keep using them.
