On approach to EGLL (Aerosoft) at 0721 this morning and suddenly all the runway lights went out; I was at 500ft on visual approach and couldn't see a thing!

Could this be the sim turning lights off as it thinks it's daylight at that time?

The day/night delimitation of the sim doesn't fit very well real day/night lighting. At dusk sim lights turn on too late and at dawn they turn off to soon.

You can add these two lines to the [Graphics] section of the config file.

DAY_THRESHOLD=48000
NIGHT_THRESHOLD=8000

you can experiment with these values because it may not fit at every location.

I searched for this in the CFG but couldn't find it to change...is it something new I should add (and whereabouts should it go)?

I'd love to know what the numbers represent...

as I wrote, add it to the graphics section.

Day Threshold controls when the lights come on at dusk, the higher the number, the earlier the lights turn on. Night Threshold controls when the lights turn off at dawn, the higher the number the longer they remain on

But what does 48000 actually translate to in the sim?  Is that number of hours, minutes, ~ time of day etc?  Was just wondering what that 48000 actually means. 

From an old FSX Phil Taylor blog 

The numbers represent the amount of 'ambient' light at the ends of the day/night blend threshold. Zero is perfect dark, 65535 is full day sun at noon in the summer.

But this seems to cancel out how it works!

I could be mistaken however I think those config entries no longer have any effect in 5.x

65535 is the decimal value of 16 threads in use in an Affinity Mask.
We can have yet another thread about which numbers to use for our CPUs - yay! 🙃

I don't think so as 65535 / 60 / 60 equals 18.20 and not 24 (hours).
Nor indeed does it equal 12 hours, the gap between the solar noon and solar midnight one would expect at the Equator in cities such as Kampala, Libreville, Singapore or Quito.

They don't. A bunch of us on Simforums tested it out and it has no effect any more. Unless the airport itself supports keeping the lights on all the time (a few do) then you're out of luck.
