I have found for one if you put Shaders and Post FX to high on settings it helps lights come in, I have tried several VisualSettings for the most realistic lights and so far the best I have found is the NaturalVision Remastered better lights for LSPDFR optional visual settings.. my only problem now is that the lights look amazing when within like 10 ft of the car but if you go any further they fade out dim and turn white.. I have tried to find out how to make them look just as good as they do when you are right there close to them from afar but am stumped on how to do that.. but for the lights up close and personal this visualsettings called Brighter Emergency Lights LSPDFR optional addon with NaturalVision Remastered looks the best.. also NVR has really good graphics and shading I think.
