It's interesting how this is marked both Dunbar-Nunn and Federal Signal depending on where you look. This appears to have been manufactured shortly after the acquisition. Cool!

This was a nice unit. One of the things I really liked about it was when I had my rear deck lights activated, I could hear an audible sound of an internal relay clicking - so I knew my emergency lighting was still activated - something my previous Code 3 unit did not (it was silent).

there is definitely something reassuring that comes from hearing those sounds letting you know that they are actually working! Same thing with the LED lights, my original whelen talons actually made a little sound but the new stuff is silent. In daylight you just have to take for granted they are working!
