What is the Siren Light Key?

Hello, i have a issue with the new update.
Now Beamng added the Map With the "M" Key. But, before that, i think it was the "Beacon" or "Siren" System.
So, what is the new key of this?

 

Go to the settings, controls, vehicle and there you have to serch for the siren binding, if you found it you can see the new binding on the right.

 

I'm I'm remembering correctly, it's now a combo. Shift + N.

It certainly makes it much harder to quickly switch on the lights and siren, especially while attempting to drive the car.

 

Oh ok, Thanks for the help!
