-

[]Optional setting to add flames to the crows nests visible from outside Megaton.
[]More customisation settings available in the config file regarding disabling radio objects, radio commercials, sound effects, lights, objects, and a performance setting to disable flickering/pulsing.

This will allow you to increase the max value of the in-game lights slider.
The default max(3500. 0) light fade is pretty low and set for the year the game released.
To be able to see Moriarty's lit up when you enter Megaton rather than when you walk closer, set fLightLODMaxStartFade=6500. 0 in the section of your Fallout.ini or add it to your FalloutCustom.ini. Then the menu slider max will go to 6500.
