Interesting, when did they allow blue lights on a fire truck? Thought blues were for Police only.
Jim
By law, no. Not in California anyway. At the federal level, yes. As you would imagine it also varies by state. Nevada uses a lot of blue. Chicago has green lights on the front right of fire apparatus.
Fun story there. Anyone know why?
Another fun fact, National Parks Service has some ambulances with blue and red lights. If you remember me saying at the federal level only LEOs can run blue, so why do some ambulances have blue lights?

It comes from the red and green navigation lights on ships. Commissioner Albert Goodrich (1927 - 1931) of the Chicago Fire Department had a nautical background. He applied the marine scheme (red light = port, green light = starboard) to fire apparatus, and the idea became a tradition of the Chicago Fire Department. He felt it made sense so on-scene commanders could determine the direction from which the apparatus was responding.
or:
A Chicago Firefighter got a ticket for running a red light. The Fire department promptly installed green lights on the apparatus, so they would always have a green light.

Ding Ding Ding. He loved boating. He carried over the navigation lights to fire apparatus for the reasons you stated. The tradition is still carried on today.
The markings are based on police car visibility studies in the U.K. by Dr. Paul Harrison regarding what colors and designs stand out to the human eye.
The research showed the human eye is most sensitive to blue/green shades at night and yellow/green in daylight.
Since the Feds took the lead on this, it may be the "wave of the future" when it comes to ambulance marking colors.

While that is true Pop, its the wrong shade of green. See the attached CA OES engine. The are painted in the color from the study.
Interestingly enough done studies were done after that first study. Painting fire engines green may actually increase response time of other drivers because they are looking for a red vehicle.
I suspect NPS went with green to represent the forest.
Anyway, the blue light on NPS ambulances is because in many national parks paramedics are also Park Rangers. This job is high on my career chart right now.
