Here in the US state of Virginia (in my area, anyway), police cars use a
combination of ultra-bright red and blue strobe lights; the BLUE is so intense
that I always look away from it-- out of necessity, because it hurts! From what
I've read, intense blue light is *really* damaging. Apparently, some of the
police forces in this country (or the police-car manufacturers) are unaware of
this problem-- either blissfully ignorant of it or just completely uninformed.
That truly amazes me. But, sad to say, it doesn't surprise me here in Virginia--
a state which *always* seems to be behind-the-times :-(
