There is a moral to this story,when something seems to good to be true it normally is, the only rear lights that look right and FIT right are genuine Ford ones. Luckily for you the seller has done the right thing.
Why not stick with your smoked rears, they were a Ford option from new so will never look out of place. I have not grown tired of them on my diamond white 2wd in the 21 years I have owned it.
