I drive a VW, and I do know that it didn't come from America's hat or America's pants (Canada and Mexico, respectively). I just have no idea where it could've come from, though. Some magical land out past the water somewhere, I reckon.
I honestly can't recall if my turn signals are amber or red. I have side markers that are amber, but I mean I can't recall what lights up in the taillight cluster. Hmm....
