The pilot revealed the reason for dark lights when the plane landed

Switching the light to darker mode before the plane landed is a very important safety rule that can save many passengers' lives.

Chris Cooke, an American pilot with more than 20 years of experience, said that leaving the lights on the plane at landing is one of the mandatory safety regulations on flights , not the flight crew guests stopped reading books and newspapers to hear the announcement, according to TIME.

Cooke explains this is a way to help passengers' eyes adapt and adjust fast enough in case of flight problems and emergency evacuation.

"Imagine you are in a strange room, bright and full of obstacles. Then suddenly all electric lights are turned off by someone and you are asked to leave immediately. Surely you will meet with many difficulties because your eyes cannot adapt to the darkness so quickly, " Cooke said.

With dim light in the cabin, passengers can see objects in the dark more easily and quickly find their way to the emergency exit along the glowing corridor. That is why the airplane window needs to be opened in case of take-off and landing to get natural light to help passengers move safely.
