Howdy!

There’s a tutorial on the Wiki for setting up a basic Day/Night Cycle here:

Towards the end, it even gives you an example when to check for Night. You could use this to toggle the Visibility of lights similar to below I suppose.

Kudos to the guys who put up the posts and video on the Day/Night cycle.

Cheers,
