Understand all that but I am assuming that the harness is there for the lights and it will be PnP and then get them activated. But until I get the car I won't know. Shall keep peeps up to date.Just a caution: I tried to add OEM fog lights after the fact once on a car (A Toyota not a MB) and it was a nightmare. It required changing wire harnesses and relays and even disassembling and rebuilding the steering column. What was a $120 option on the sticker was approaching $1000 to do afterwards. You risk throwing service errors or melting wire harnesses if you do it incorrectly.
I am looking for that part number. It's really difficult as all diagrams refer to pre-facelift!
Thanks ! i think i meant to say the plastic around it
The "fog lamp assembly bracket" is the plastic around it in terms of the front bumper.
The assembly itself is the plastic around it from the LED bulb's perspective.
Or perhaps you're referring to the semi-cone shaped portion of the lower valence within which it resides? See "Center Cover" piece #7 : Bumper & Components - Front for 2018 Mercedes-Benz GLA 250 | MB Online Parts
btw: it appears from the "discontinued" in the parts list that at one time the surround was a discrete valance piece but now fully molded-in.
Here is a way to check you assumption:Understand all that but I am assuming that the harness is there for the lights and it will be PnP and then get them activated. But until I get the car I won't know. Shall keep peeps up to date.
