The screenshot looks like it's just about dawn or dusk, where street lights turn off/on. Is it still the same when it's completely dark and in the middle of the night?

If you share your output log (player.log on Mac and Linux), we can compare the mods and see if there are any errors, which would explain what's happening. This guide explains where to find the log and suggests some places you can upload it to, since we can't attach files on Steam.https://steamcommunity.com/sharedfiles/filedetails/?id=463645931&searchtext=log

Side Note: For myself it is all the streets lights within the city that are not working, this includes freshly started cities as well.

Probably not related to the issue, but I noticed you had some broken assets, which I recommend you fix. The Loading Screen Mod can help you find the networks you are missing for them, or help you identify which ones they are in case you just want to remove them. You also have 2 local assets (sawmills) which are broken, which I would delete. They are missing some vital info and probably not worth trying to fix.On to the street lights. Are they off all during the night? Or do they turn on at some point? Is it all roads or just some?I see you have Electric Roads Mod 2.1, which has a feature for only turning lights on, that have electricity. Check the settings for the mod to make sure it isn't the mod doing exactly what it should. You can also try disabling the mod to see if that turns your lights back on. That would tell us if it's related to that mod or another one.
