Solved Police lights on Grand Marshal not working

So, when i'm trying to activate the police lights on the grand marshal, they don't go on, the hotkey I use it shift+n, it works on all my other vehicles, and the only mod I have installed that might interfere with the police lighting is the realistic police lights mod by WarDaddyUSA.

Thank you!

Update: I got it fixed by changing the key I use to activate the lightbar, thank you to everyone who commented telling me tips!

 

Maybe try to clear your cache. If not then idk but thats the only way i know

 

i use shift+m

 

To anyone else reading this thread, if you for some reason don't want to change the key bindings, you can also uninstall Openable Mod to avoid binding conflicts.
