All the threads I have seen on the various replica foglights discuss the harness, switch, etc, but none seem to say if there is any difference in the foglights themselves. My car had the OEM switch and harness all in place when I bought it, so all I need are the lights, brackets, and bumper surrounds. Does it matter where I buy these from, or are they all coming out of the same factory anyway?
they are made in different factories, hence the different qualities, different hanresses, etc. There was a whole long thread that detailed all the options, search and I think you will be pleased to find that.
