Several lights in the scene are correct while the part is displayed in black. I made a copy from propper one and it is still not working.

It seems this is a different issue (based on a Facebook convo).
We will need a scene to look into it (I haven't checked it yet, so sorry if it's already there).

Which version of Corona was this scene made in? The lights render pure white for me in 14.09 v3 daily.
Update: sorry, they sometimes render white, sometimes black o_o

Ok, I think I got it:
-check what render element you have selected in your VFB
-if it's LightMix, then one of the lights will be black, because it's included in the "rest (unassigned)" category of LightMix
-if it's Beauty, then both lights will be displayed as white
The reason why I sometimes got black and sometimes white lights was that different render elements were displayed depending on whether I launched IR or regular render.
