If you don't have Euro lights, just the standard US lights, then your headlight /lens is seperate from the foglight/plastic lens. This seperate fog light lens covers the fog light and is connected to and part of a plastic frame that surrounds the headlight, no? If yes, this part is called a 'headlight door' and MAY be what Fastlane is calling a 'headlight rim or frame' - the price is about the same ballpark for the 'door'. Give Phil a call on the 800 # and confirm this.
However, given my druthers, I'd druther apply the $180 a pair of these doors cost towards the $300-400 cost of Euro lights, if I really wanted to clean up the front end. (Pic below). Hope this helps.
