Fehler mit : AttachObjectToVehicle

Hey Leute,

Alle Dinge mit AttachObjectToVehicle
funzen bei mir net. Sirene und Neonrähre kommen nur ganz selten.
Ansonsten buggen die immer rum, weiß jemand warum ?
(Nutze SoL)
Lg

Beispiel:

AttachObjectToVehicle(sirene[GetPlayerVehicleID(playerid)],GetPlayerVehicleID(playerid),0 ,2.6,0,0,0,0);//Vorne Mitte
AttachObjectToVehicle(sirene1[GetPlayerVehicleID(playerid)],GetPlayerVehicleID(playerid),-0.5,0.0,0.85,0,0,0);//Dach sirene
AttachObjectToVehicle(sirene2[GetPlayerVehicleID(playerid)],GetPlayerVehicleID(playerid),0.7,2.6,0,0,0,0);//Vorne Licht Beifahrerseite
AttachObjectToVehicle(sirene3[GetPlayerVehicleID(playerid)],GetPlayerVehicleID(playerid),-0.7,2.6,0,0,0,0);//Vorne Licht Fahrerseite
AttachObjectToVehicle(sirene4[GetPlayerVehicleID(playerid)],GetPlayerVehicleID(playerid),0,0.9,0.4,0,0,0);//Mittig im Fenster
UCL[GetPlayerVehicleID(playerid)] = 1;
SendClientMessage(playerid, COLOR_YELLOW, "Sirene angeschaltet.");
