A Brief History Of Emergency Vehicle Lights And Colors

Nowadays, emergency vehicle lights are generally recognized, but that hasn’t always been the case. In fact, before the introduction of emergency vehicle lights sometime around the early 1900s, there wasn’t an easy way to differentiate police cars from civilian vehicles. Emergency vehicles looked pretty much like any other vehicle on the roadways. Because of this, police chiefs regularly used convertible vehicles so that regular pedestrians could see their police hats. A couple of decades later, at the beginning of the 1930s, red lights were added to the tops of police vehicles to signal civilians that an emergency vehicle was nearby.

This quickly became the standard and developed into the revolving gum-ball light in the early 1950s, followed by horizontal lights in the 1960s. Afterward, blue lights were also integrated into the emergency lighting scene at the end of the 1960s to help people with color blindness distinguish between colors.

Presently, emergency vehicles are fitted with a broad range of emergency vehicle lighting, the type depending on the vehicle’s service, state, and agency. Nevertheless, regardless of the state’s law on emergency vehicle lighting, it’s apparent that they are essential to every driver and pedestrian’s safety on the road.

What Colors Are Emergency Vehicle Lights?

1) Amber Lights

Amber is one of the most commonly used colors for emergency vehicles. Mandated in over forty U.S. states, amber lights are in most cases used on wreckers, tow trucks, construction vehicles, public works, and escort vehicles and serve as a rotating spotlight for a truck that frequently works on an open road to signal other drivers and pedestrians that there’s an active working site nearby. They’re also utilized by police vehicles used to direct roadway traffic.

2) Red Lights

As you may know, red lights of all types are instinctively associated with emergencies and are most commonly used in fire trucks, ambulance vehicles, and police cars.
