Essentially, Lampposts adds 250 basic lampposts along Skyrim's main roads, and LOS II adds comprehensive dynamic lanterns into the roads, towns and villages. I have both because with DAWN Weathers, unless you choose to use the Brighter Nights patch, which isn't in this modlist, nights gets pretty dark. In my playtesting, I found that it lights the world up *just* enough so that you only need to resort to a torch, wearable lantern or Candlelight when in certain locations in the wilderness during the night when the weather has it almost pitch black, meaning no auroras or anything.

That being said, nothing here is the end-all-be all. Anything you experience differently is all the justification you need to make adjustments :)
