This is a modification that allows you to change any of the supported vehicles' emergency lighting from red and blue to all blue by simply Drag and Dropping a ytd file in openiv. If there is a model that you want with all blue lights, let me know and i'll add it.
Thanks @mellowyellowbudy for the donation!

I will have to work on linking all of the models again. It seems there's a new system that got rid of my list...
