Blue is more visible at night, but not during the day.
Most people are unaware that there is a significant amount of research that has gone into understanding which colors are most visible during the day, night and in which age group. Whether it's on Youtube or on a forum like this one I'm constantly running across comments which say that such and such a color is better than such and such a color because of xyz. In fact, most people are clueless. Most people talking about red, blue, amber or clear lights have absolutely no idea about which color is the most visible during the day, the night, in the city, in the county, for an old person or for a young person. If anyone would like to finally have a clear understanding of this question, keep reading.
A study done in 2008 called the "Effects of Warning Lamp Color and Intensity on Driver Vision" was conducted at the University of Michigan Transportation Research Institute in Ann Arbor and was underwritten by the Department of Homeland Security, the Federal Emergency Management Agency, the United States Fire Administration and the US Department of Justice. The 54 page study revealed that
blue was the
most conspicuous color day or night and in any age group. The report strongly recommended that emergency services throughout the USA begin to put
blue on all vehicles.
This is what is now happening with FDNY.
We can all speculate about which colors are most visible and I'm sure that we all have our preferences based upon which cop shows we watch on TV or upon the colors used in our own state or country, but the fact remains that if we are just saying that such and such a color is safer or better than another color when in fact we are totally clueless regarding current research, then we are just making everything up and it's meaningless. And it shows.
The report that I mentioned above is available in PDF format on the internet and I
highly recommend it to anyone who is truly interested in understanding the question of color and conspicuousness and why blue is now coming into fashion for some emergency services which never used it before.
Concerning FDNY Squad 18's front blue rotator, it is, to my knowledge the only FDNY apparatus with a forward facing blue light. This is just the beginning. I am confident that someday, perhaps not this year or next year, perhaps not even in 10 years, but someday
all FDNY apparatus will be equipped with not only rear blue lights but forward facing blue lights as well.
I'll soon be posting more videos of FDNY Squad 18 and its forward-facing blue rotator! ;-)
