P5 - PANC - may I turn the runway lights on by day ?

[Tozzifan 7]

Hello,

I've just started using PANC in P5

 

I've done three day landings with 747s, always into a foggy area, so I wonder whether runway lights are turned off by day, also in real world

 

and, regardless of real world , whether I might turn on runway lights by day, anyway 

 

thanks
