Blamer... it is possible that in order to have this lighting effect it is necessary to have to install AC Content Manager alternative launcher?!?!CM is an alternative launcher. I think you HAVE to use it in order to have working lights...
Your choice
Apart from the fact that to enable the various mod you have to buy the "pro" version by making an offer to its author because in the free version this option is disabled, I think the mod related to the cars light it can also be enabled using other programs such as JSGME...
So I can not understand why, although I have installed Shaders Light Patch v0.1.21 does not work...
Perhaps to be able to function properly, other addons are needed?
