I know this probably won't change until people figure out modding, but I believe nights are way too bright.
Now, I do not want pitch black nights, but currently the only difference between day and night is the tint of the sky and surroundings, the visibility is pretty much the same. I know one can see fairly well, even on moonlit nights, but in Far Cry 4 they feel and look like cloudy days. The lights coming from buildings, camp fires and headlights aren't pronounced enough due to the brightness, which is a pity, the game has some nice lighting effects. I mean just look at the lights in a cave.
I understand there are more pressing matters to fix, but please, make the nights a bit darker.
Depending on your system you can darken this yourself, I know on the Console versions there is a check to calibrate your brightness, I lowered mine a bit after thinking like you do and it did help somewhat although I know where you are coming from! The lighting changes depending on whether the moon is visible too, however I am not the sort of gamer that likes to hold a torch in one hand and a gun in the other to be able to see either.
