How does one go about finding the part numbers for these?
I have seen them on a 2017 GLE, they are now standard on the 17 GLS.

From the MBUSA site....
Side-mirror logo projectors
Standard
When you remote-lock or unlock the vehicle, special filters and LED lamps beneath each side mirror project the classic "Star and Laurel" logo of Mercedes-Benz on the pavement. In addition to welcoming you in unmistakable style, the illuminated logos help you see puddles or uneven pavement as you approach your vehicle.

Has anyone successfully installed these lights on x166. I am interested in getting this too and looking for the right parts.
thanks,

1st - Mercedes does not offer a Puddle-Lamp-Mirror "upgrade" kit.

Please check at the bottom of each front for the the type/look of courtesy lamp in you rig.

Depending on the "style" of that bottom door courtesy lamp - there are China suppliers that make replacement courtesy lamps with added logo projector - which will project a type of Mercedes logo when door is open/over the ground.
