The problem is that when I install the emergency light system mod, it crashes the game after starting the game for a single player. After removing els, the game works again. I have no idea what the problem is. I would like to ask for help.

It is not unlikely that Emergency Lightning System will not give problems, in fact it is a mod that has not been updated for a long time. Is this your first time installing it? If you have already installed it in the past, has it ever given you problems?

I only have lspdfr and els, now I removed els to be able to play normally and downloaded some other mods not related to this. However, they have no effect because els before installing them didn't work anyway and it crashes. Before, I had a lot of mods and els. I've never had a problem like this. Recently I removed all mods and is reinstalling one by one. Just when installing els, the game crashes after turning on story mode.

Unfortunately, there are no mods similar to ELS. You can try to install, in principle, a mod that changes the tone of the sirens, but it is not the same thing. The only thing you can hope for is that it will be a temporary crash and maybe you can try to install ELS later
