Hi I restore tail light and park light housings. You can get really nice generic sockets at many auto parts stores. I am in Canada so the following doesn't really help you I assume, but Canadian Tire has some superb ones that fit in really nice and have good plating and look quite close to originals. With work you can even duplicate the weather seal jacket typically used on many front turn signal/park lights. Hope that helps
