No police car I can select has working lights. I can hear flicking but nothing visual. I have installed ELS 8.0 as well. No AI car will pull over for me and the game crashes constantly. I have tried the Diagnostics tool and that fails as well. I have attached the log but that shows nothing and several of the crashes. I am running windows 7 64bit. I have both GTA 4 and the liberty city add ons. This happens in all 3 GTA 4's, the original, and both liberty city addons.
I also noticed that the AI police cars, the ones with light rack, when they are code 3 their light disappear and reappear.
