As of now, the Night light is almost a forgotten structure. Could be because it's expensive to use especially in early days. I was thinking, the feature of Maxwell lights could be implemented into these. It means, they could have a fuel tank ( filled with nightmare fuel ) and when a player approaches, they would light up, just like the chandeliers in the archive biome. They would consume fuel while lit, and turn off when player leaves the area. Their fuel consumption rate can be increased to cover of the extra feature.
It would be both aesthetic and useful to see this. What do you think?
