Paul,
I liked the looks of the tail lights also and got a pair of APC Fiber one's for my silver PT. They look great and it stands out from the normal PT. Some people (including myself) are seeing strange things on the clear cover. Mine have what looks like small scratches on the inside of the lense on the right rear light...not enough to hardly notice, but other have had condensation and lots of "scratches" on theirs and one person has sent theirs back twice to the company for replacement. There's a lot of people that have them and only a couple of bad reports so maybe they all don't have the problem of scratches and condensation. They fit nice and go on and off without any trouble. Their a little expensive (unless you get a good price on ebay like I did) so use a reputable dealer and keep the receipt so you can replace them if need be.
