So you were able to swap the old circular halogen lights, for the newer LED lights?
Here in the US, 2022+ GT-Line have LED headlights, except they are of the reflector type. This wa pretty much right after we drove our '23 GT-Line home.
The reflector type LED headlights actually work quite well. However, I had already bought a set of the projector type GT1/GT2 headlights off ebay, originally intended for the red '19 2.0T. So, I ended up putting the projector headlights into the '23 GT-Line. Since the OEM reflector headlights were already LED type, this swap was an easy drop-in plug and play.
The adaptive swiveling part, of course, does not work, since the GT-Line does not have the provisions for control headlight movement. But... that's really not that big a deal. I was able to adjust the aim properly via the manual adjustment screws, and the headlight beam pattern are broad enough I really don't much mind them being static (non-moving).
So... the reflector type LED headlights from the '23 GT-Line will be swapped into the '19 2.0T. This swap is a bit more work, as the OEM headlights are halogen type. The headlight circuits will need DC-DC buck converters. The turn signal lines will need load resistors. I got them both off Amazon and will be installing them soon. There are threads on this exact topic. Do a search and you'll get the details.
