That's bad. I said before, SCS kill weather modding. Why? I don't know. But I can send you my unfinished weather mod (SCS default) where I hit to "albedo-based" light curve in index [0]. So, I hope, it can help you with your mod. But at first, you must create correct "lighting" settings for dashboard panel at day and streets lights at night, then (if you patience is not finished ) create weather look settings. Here no another way with "new lighting system" from SCS.
EDIT. Here is my SCS ATS weather setup files. I repeat: this is UNFINISHED version, so is you use it in game, you may see wrong lighting.
But here "min\max adaptation" and some other HDR parameters group is correct for bright dashboard panel for default trucks.
JUST FOR TESTS ONLY - NOT FOR PLAY
