This mod file removes the screen dimming effect whenever you pass by any source of light in-game.
The first screenshot shows me directly below a street light which normally would make my screen go darker when I drive by it and then go back to normal again, 
but with this mod, when you drive by any light like a streetlight or traffic light for example, it will not dim, therefore making the overall experience much more 
realistic and less annoying and gets rid of rockstar's eyesore.
