I am wondering where you can purchase the chrome fog lite covers for my 2007 GL450?

 

sean....I have been involved in an extensive search for the same thing with many aftermarket vendors as well as Mercedes. If you currently have the standard, black plastic covers that fit around the round lights, you are out of luck. I am looking into purchasing an additional set of covers, and sending them out to be chromed (don't know by who yet). FYI, my dealer informed me of the following part numbers for these covers: 164-885-11-23 and 164-885-12-23. I was told they cost only $14.95.
The chrome covers for the oval lights that come with the P2 package, apparently cost $69.00 each. These part numbers are 164-880-07-24 and 164-880-08-24. I question the accuracy of these prices, though they are for the covers only, not the lights. I understand someone tried using the chromed, oval cover with the round light and made it work. I don't know that I want to go there. Hope this helps you a little.
