I am considering either installing a Stebel air horn or the dual BMW horns from an 2005 model. I probably want to go with the Stebel but am wondering if one can give a more modest warning or if the horn is activated at full blast each and every time. Sometimes it's appropriate for just a little warning, and sometimes it's better to make them think it's coming from a transport truck. Can anyone shed some light on this?
Thanks!
Thanks!
