I don't know about Accord.
I know that why everyone refers to amber corners as JDM started beacuse of JDM Vision corners for the EG Civics.. (they were available for EFs, but extremley RARE, and super expensive) Then there started to be a couple USDM companys that made amber corners for EGs, and now they're starting to make amber corners for EFs, but there's nothing JDM about them. They're made and sold on/for the US market.
