Fireflies is a mod for Fallout 4 that recycles a vanilla radiation visual effect from the Glowing Sea, and uses it to spawn fireflies during night-time.
They may appear in forests and inland rural regions of the three main worldspaces of Fallout 4, the Commonwealth, The Island and Nuka-World to add a bit more immersion to your night-time adventures.

Under Time Settings you can set the hour when fireflies should appear, and when they should disappear.
Under Density Settings you can change how often it is a dense versus a lighter firefly swarm.
Under Color Settings you can change the color of the fireflies.
You can also set whether fireflies should disappear when the shooting starts, or if they should ignore combat altogether.
Of course all these options can also be set in the mod's own MCM menu if you're on PC and have MCM installed, but MCM is not a requirement, this is only an optio
