Golf vents aren't illuminated, Jetta are. I didn't bother with that.
A little more detail ...
Golf vents aren't illuminated (maybe gasser MK4 R32 were??).
Most Jetta were up until either 04 or 05, then only (gasser) GLI vents were.
These are typically easy to find, but hard to find in decent condition - flaking paint/coating and busted vent slats. Especially the drivers vent/headlight switch surround.
If you go "yard hunting" for a set, take the time to go as deep in the dash as you can to get the car side connector and as much lead/wire as you can.
Take some old credit cards/firm gift cards with you, they work well to get in between the dash and the edge of the vents to get them out without marring the edge or flaking off the black coating. Don't forget the torx screw in the drivers and center sections ... and maybe the pass side one, can't remember.
At one time I had some OEM NOS center vent surrounds, but I think I installed/sold all I had.
