You give no idea of your age, education or aviation backgound.
So assuming the worst:
Lights enable you to see in the dark.
Landing lights enable you to see the ground when landing.
WWII aircraft had to be able to land in the dark if necessary.
WWII runways did not have lights like today and were identified (if they were expecting you) by rows of things called goosenecks near the runway.
A gooseneck was a metal watering can like device full of paraffin with a wick sticking out of the spout which when lit gave a pale flickering light.
A goosneck was visible for about a mile (which is some 1.6km)
Dunsfold had no lighting in 1968 and so I had to use goosenecks when I was asked to check out a Harrier at night. Since my takeoff blew out all the bloody goosenecks and I had to wait some 20mins until they were lit again before I could land, I went down town Godalming and bought some battery powered lanterns the next day.
The man whose job it was to puchase equipment for the company (the "Buyer") became irate some weeks later when he was advised about what I had done. By then we had finished the night flying to the Ministry's satisfaction so I told him he should thank me for avoiding him being personally responsible for a programme delay. Not sure he got the point though.
