Hello guys!
At last I solved, with the user selyb, the issue about red lights for who have Dawnguard DLC installed.
There is a new Main ESM file now just for Dawnguard. Use this one instead of the other main ESM if you have that DLC.

If you want lanterns in the Dawnguard DLC worldspace too, download and install this patch too: http://skyrim.nexusmods.com/mods/26662

A special "Thank You" to selyb!
