In PA.....
Police uses red and blue, typically in a half and half configuration with some white to the front mixed in and sometimes some amber to the rear.
Fire and EMS uses mostly red. Typically with some white to the front and some amber to the rear mixed in. EMS has some additional regulations in addition to the motor vehicle code from the DOH. Ambulances are limited to one forward facing white light, but can use 2 if they are in a lightbar. They are supposedly limited to 2 rear facing amber lights, but I commonly see units with 3. Some utilize amber to the front, but not more than 2.
Fire and EMS department members can utilize blue lights (with no siren) on their POVs, but doing so does not enable them to disregard any laws like actual emergency vehicles can. Up to 3 Chief Officers of Volunteer Fire and/or EMS departments can utilize red lights and sirens on their POV and are recognized as an emergency vehicle when doing so.
Amber only is tow trucks, DPW and other service type vehicles.
