Need help with lights

[Löwe]

Hello, is there any way of modifying .ini files or whatever through kegetys method to make the airdrome lights turn on earlier? Because if you want to see them, you'll have to play at 10 pm I think, and you can't see anything, so it's not enjoyable. (yes, I tried playing at 4 am but they won't turn on) I want to make them turn on at 18:30. Is there any way to achieve that?
