What does just blue lights on a police car mean?

Police vehicles such as squad cars, patrol cars, and highway traffic cars have gone through many changes over the last few decades. As the need for better police cars is increasing, they are going through some heavy modifications and customizations in order to suit the current requirements of law enforcement personnel. 

Early four-wheelers used by officers were inadequate and barely capable of giving a chase to suspects. Since then, cars are specialized at a mind-boggling rate for police use. 

Multiple features of squad cars have been standardized all over the world to suit the current policing situations. One of these features was emergency vehicle lights.

We all have seen emergency police lights in real life or on TV. They are mostly a combination of red and blue lights.

Apart from that, most vehicles consist of red color tall lights. 

Thus, it makes sense to add a rare yet attractive light as red-light bars could instantly get lost in the crowd. Even when it is rotating or flashing!
