Add on police cars and coronas?


I’ve downloaded few police cars for our PD, but their light bars are very badly visible. I don’t wanna use any client-sided mods, I would rather fix the coronas on those vehicles by myself.

Unfortunately, I don’t even know what I should be looking at. Could anybody give me advice? Even better, did someone already do this?

Thank you for all answers!

Did you figure this out?
