Firstly make it clear that When Pilot Initiates Take Off roll, and sets the Take Off Power, the Cockpit Lights are Closed, only the Over Head Panel and The Gauges Lights are open....
Secondly, Cabin Lights are Switched Off by the Cabin Crew..
Thirdly, In the interest of safety, passengers need to have a clear view of what is happening outside, a dim light allows the eyes to adjust itself for this purpose.
& to save power as maximum electric power is required during take off when several complex electrical equipments & high intensity lights are used...
During takeoff, descent and landing, cabin lights are switched off so that in case there are any problems, the crew can look outside through the windows (especially at night when it's difficult to see what's outside with lights on), they can alert the pilots.
For instance, if there is damage to a wing, the pilots can not visually see this but the crew can, and notify them.
Switch off lights while taking off is an international signalling code approved by the concerned bodies in aviation for all aircratfs that is taking off. Switching on lights and opening the windows while preparing to land is an international signalling code for all aircrafts that is intending to land.
For the flight to take-ff,lot of energy required.Gas Turbine that is propelling the Aircraft will have more power by reducing all unwanted Power consumption
I think that is not very convincing either....If that is the reason then the pilot could keep the cockpit lights turned off all the time, why the passenger cabin lights need to be turned off that too only during take off. It is again turned on when the aircraft attains a certain altitude.
The green line on the floor in aisle is there to appear illuminated in case of power failure due to some emergency.
