I saw something in a fedsig parts list about it but I've got no idea what exactly it means.NPS Ranger said:Who knows about Swedish blue, which is different?

I thought that within Europe, what we call "CIE Blue" is just called "Blue".ERIC6913 said:ok people lets get this straight. outside of europe its designated/called, cie blue. inside of europe its designated/called "R-65" blue.

The lighter-blue LED color in some Liberties isn't intended to be there. Whelen gets their LEDs cheaper if they can allow a wider color range in the "blue" category than the typical deep royal blue that ought to be used, which requires more precise manufacturing (or something like that). It doesn't have anything to do with American or European lightbar colors - that's mainly only intended to cover strobe and halogen lights.FGS said:If deep blue is for europe and light blue is for US. How come I have seen both of them here in Liberties? That's just for one department. They use both shade of blue on their PD cars. As much I love the deep blue LEDs but seeing both shades made me wonder.
ERIC6913 said:no, they actually have a different shade of blue for each technology, i.e. halogen, strobe and led. the most common being R-65 blue for halogen. European Regulations are much more specific and closely followed. If a light is not approved for use, then you are not allowed to run it.
RJ* said:Yes and no. ECE R-65 (or just R-65 for short) is actually the document regulating all warning lights - be they halogen, strobe, LED or whatever. R-65 only recognises blue and amber as warning colors. The full text can be found here:

IMHO, the document is a bit confusingly written, and needs to be redone due to advances in lighting technology.
