I get mine off amazon and btw, I just installed some more on a customers car and the switchbacks worked. Only thing that was different was hers were wired to a switch with just the amber tapped into the blinker. Not sure if that matters or if the led strip was a newer version. They did look different in color, more of a reddish tint.
