Ever since I installed Natural Vision and Visual V, my lights became blue and yellow. So then I tried fixing it by installing the "very bright" visual settings of Radiance as I had just bright before. Doing this made the lights change only at evening and night but not during the day. The lights were still blue and yellow during daytime and normal at evening. And at night, the lights become extremely bright. Anyone got a fix for this? 

Open OpenIV and go to mods \ update \ update \ common \ data.  Extract "visualsettings.dat" to your desktop and open it.

 

Find the following "car.defaultlight.emissive.on", there will be a day and night option.  For day, change it to 6000.00.  For night, change to 1500.00, then save.

Now, in OpenIV, click "edit mode" and drag the edited visualsettings.dat back to where you got it from.  Click "edit mode" again and you can close OpenIV and go in game.
