I solved the problem, but my question is, why is no visible the red/blue light on the walls? All is good, is looking nice, but is only on the lightbar. It doesn’t reflect on any object. Like there is no light source… I found on lspd forum every sirensettings values, so 1 was for me (before, was setted 3). I will try tomorrow more. Maybe that value is not for my car.
