Lighting Up Megaton adds lights to areas that are hard to see at night even with the pip-boy flashlight on, this is something i have come across as i played the game mainly because i didn't blow up megaton so im going there a lot the one problem i have is finding stairs and ramps because there in the pitch black and the stairs and ramps are a dark colour its hard to see them even with the pip-boy light on, so i added a few fire barrels where i commonly go the problems.
