This mod only affect exterior lights, so it works perfectly with RLO (without exterior lights), ELEFx and ELE. It is a shame it is not compatible with Relighting Skyrim. I used Relighting Skyrim with LoS and I liked it, but i hated the lights candle always on along the roads or in the mills. With this mod I have candle on the roads, but they switch off gently in the morning. And I love it. It is a must to me. I don´t use ETaC so I have no conflict at all now. The only mod i lose is Relighting Skyrim because moves/modifies some exteriors lights. I had CTDs using both.
