Fog light Replacement
I have a cracked right fog light on my 2009 CLK350 My car has the round lenses (AMG Grill). The dealer gave me a part number of 204-820-21-56.
Is this the correct part number?
I've seen many eBay listings for used Hella replacements claiming to be OEM....Is this true?
How difficult is it to change it out? Any tutorials?
Thanks
