This is a fix for the Vanilla Taxi rooftop ads To keep them from being blindingly bright while keeping the visualsettings.dat intact. 
This does not edit visualsetting.dat, it is just a texture replacement for the taxi's, so your emergency lights keep looking great.
 
DISCLAIMER
I know that the colors have been distorted, I am not a Photoshop master.
My goal was to reduce the glare and I feel I achieved what I wanted. I wasn't going to spend a lot of time editing something that isn't important( I  spend close to zero time in the taxis and I never just sit and look at the ads) to my game play, from afar it still looks like an advert and doesn't blind me when I'm on patrol.
So keep that in mind if reviewing.
If you want it to look better, I invite you to make the edit your self.
