I just reinstalled the game & Mod after a Windows reinstall.
I also installed a couple of ELS police vehicles. And for some reason, when I go into the game to check the vehicles, their emergency lights come on automatically as soon as the driver starts the engine. But only a couple of the lights come on and stay on. I can't turn them off, nor can I turn on any. They're bright, so apparently Radiance V is working.
I used OpenIV to install the new vehicles in their correct path. I also covered their config XML files in the ELS folder. But same issue remains.
Not sure what is going on....
