Las Vegas Valley Apparatus

[nozzleman]

In Arizona, for example, by state law police are authorized to use Red/Blue, fire is supposed to use all Red (but many fire Departments ignore that and go with Red/Blue) and ambulances can use Red or Red/Amber (amber has pretty much disappeared except on really old ambo's). California fire apparatus must have all red warning lights and all emergency vehicles must also show a steady-burning red light to the front, as well.

 

To me the more lights and different colors that they use make them more noticable. I know in Nebraska the volunteers where allowed can use red lights but not sirens.
