I'm enjoying the mod so far, I did have to change the tint in the vehicles.meta file. Incase anyone else has the same problem, with the vehicle tint being too dark. This could be something that, I'm just too naïve to know how to fix, but the no plates does kinda spoil it for me. Awesome mod though, its a solid 9/10
Do you have ELS installed? (Emergency Lighting System) It let's you use the 3 stage lighting by hitting the "J" key and the top number keys 1 to 6 for your sirens.
