Similar situation...the U.S. fire fighting community starting using European-style reflective chevrons in the 2005-2010 period. U.S. apparatus spec is governed by something called NFPA 1901 but is highly decentralized and people were mounting them upside down even though they were conforming to the (nascent) standard for rear reflective surface area. The "V" shape of upside down chevrons can pull people TOWARDS a vehicle vs. direct them away from it. Mostly fixed now but a hot mess.
