As the title of the post suggests, I had been using els lighting on a variety of different vehicles that I've downloaded and then, as of tonight, I no longer have any functioning lighting on any of these vehicles. I haven't changed any of the game files since I last played, which was only two days ago and when ELS was working fine and everything else seems to be doing what it's supposed to do (I have many plugins that I'm using). Any help or recommendations would be greatly appreciated. Thanks for reading. 

For the record, I just went ahead and restarted the game a few times after unloading and then reloading all the plugins and that seemed to remedy this otherwise inexplicable problem. Ghosts in the machine as they say in the Matrix.
