That's just the colors that they adopted. Some states only use red or blue, not both.

Police car lights are red and blue because these colors have high visibility and can be easily seen from a distance. Red is traditionally associated with emergency services and signifies caution, while blue is used to grab attention and indicate the presence of law enforcement officers. The combination of these colors helps to quickly alert people to the presence of a police vehicle and encourage them to take notice and respond accordingly.

Why are police car lights red on the left and blue on the right side?
For the same reason airplanes have red lights on the left and blue lights on the right. If, in a poor vision situation, two police cars (or any emergency vehicle for that matter) are some distance apart and racing down a highway (or two planes in the sky) and see the flashing lights of another directly in front of them, they know by placement of the lights whether they are following the other or are in a head-on situation.
Street lights that use high pressure sodium vapor produce light that is mainly yellow with some red why are dark blue police cars not advisable in a community that uses these street lights?
When illuminated with white sunlight, a dark blue police car reflects mostly dark blue - which you see - and absorbs all the rest, such as red, green etc. It is similar with any object of some color. If the light comes from a sodium light which is mostly just yellow and some red, there is basically no blue to reflect from the car which, in the spectrum between red and blue, reflects only blue. Therefore the car will appear black or rather very dark and hard to see.
