Lights but no sirens

Okay so I input new cars in my five reborn game and I hit the sirens and only the taillights will flash. So I was wondering if maybe I needed ELS so I did and I can turn the lights on but the sirens wont work at all unless I turn off the siren and only use the lights. I use a controller so the left arrow on the D-pad works for the lights but once i turn them off and use the analog stick for the sirens, only the taillights will flash. Any help?

ELS cars and the plugin are not supported by Fivem, ask the author of the cars for support
