Why are Police Lights Blue and Red?
When we see police cars speeding down the highway, what’s the first thing that catches our attention? The flashing lights, of course! Those bright blue and red lights are a beacon of authority, signaling to us that the police are on the scene. But have you ever wondered why police lights are blue and red? In this article, we’ll delve into the history and significance of these colors, and explore why they’ve become an iconic part of law enforcement.
A Brief History
The use of blue and red lights in police vehicles dates back to the early 20th century. In the 1920s, police departments in the United States began to adopt flashing lights on their cars to increase visibility and safety. At the time, most police cars were equipped with white lights, which were not as effective in low-light conditions. Blue and red lights were chosen because they were more visible in low-light conditions and could be seen from a distance.
Why Blue?
So, why blue? Blue was chosen because it’s a color that’s easily visible to the human eye, especially in low-light conditions. In the 1920s, most streetlights were yellow or white, which made it difficult to see blue lights. Blue lights stood out against the yellow and white lighting of the time, making them more effective for nighttime patrols.
Why Red?
Red was also chosen for its visibility. Red is a color that’s easily visible in daylight and nighttime conditions, making it an ideal choice for police lights. Red is also a color that’s associated with warning and caution, which made it a fitting choice for police lights, which are meant to alert the public to the presence of law enforcement.
The Standardization of Police Lights
In the 1950s and 1960s, police departments began to standardize their lights, adopting the now-familiar blue and red color scheme. The International Association of Chiefs of Police (IACP) and the National Highway Traffic Safety Administration (NHTSA) played a significant role in standardizing police lights. The IACP recommended that police lights be blue and red, while the NHTSA standardized the design and installation of police lights.
