Yep, Mine stopped working randomly as well tonight. All was fine. I legit was playing with ELS working. Closed the game. Came back a few minutes later and relaunched the game (Nothing was messed with or installed) and the lights do not work on any car that I have installed now. I've reinstalled the asi loaders, reinstalled scripthook V, reinstalled ELS to no avail. Not exactly sure what has caused this but it is very irritating, hoping to find a fix soon. I do have backups of the game but I'm not sure if that's an appropriate route to take right now.
