<i>I have never seen an ambulance with this device installed</i>

I worked as an EMT in Virginia. We have little boxes with narrow tubes on their faces, pointed at oncoming traffic. These are <em>sound</em>-activated, and we had to use a specific siren setting when approaching an intersection with one of these devices. The tube on the traffic signal box was basically a waveguide, to reduce sound from other directions.
