If you are using CEP2.3 or higher, have a look at the Placeables -> Custom -> Civilization Interior -> Lighting
The Candleabra 4x placeable is a good one.
It comes with the scripts needed, and the variables you can use to turn it off during the day, or On at night, or on always etc, and customize the color/brightness.
Note - this is placeables specifically.
If you mean Torches attached to walls, in the form of tilesets - the best you can get is modifying the tile in toolset to have night version of the map, with torches on, and daylight version to have no lights on.
(I think thats done either via setting the torch light to black, or setting the animation checkbox to be off?)
