Custom sirens problem

[Dzsozi (h03)]

Hey guys, today I made custom sirens for police cars, but my problem is that I don't know how to attach it to all police cars, not a specified one. I made something like that (I think), but it's not working. Heres my code:

function policeSirens( ) 
    local occveh = getPedOccupiedVehicle ( localPlayer ) 
    local id = getElementModel ( theVehicle ) 
    if id == 596 or id == 597 then 
        setVehicleSirens ( occveh, 7, -0.800, -2.849, 0.050, 60, 118, 224, 255, 255 ) 
        addVehicleSirens ( occveh, 7, 3, true, false, true, false )  
    end 
end 

So how can I attach these sirens to all police cars with id 596 and 597? I hope someone could help me in this, I would be grateful. Thank you!

Any errors?

If no errors then:

Note: Although you may be able to add sirens to any vehice, this function may not work. This function fails on the Buffalo for example.

@Dzsozi

There are warnings. /debugscript 3 to see them.

And next time put them at your post.

Okay, sorry about debugscript But it's not working as well. I tried it. Is this worked for you?
