They are superb. I have always managed with the ordinary headlights in every vehicle I have had. The LEDs were part of the package I got with my demonstrator. Some of the extras I wouldn't have paid the premium for them, but the headlights I would have done.
Unlike the ordinary lights which are a yellow light, these are bright white. A friend has uprated the lights in his California with more powerful bulbs above the standard and they are still nowhere near provideing what the LED ones do.
Here is one thread to have a look at

They seem to have a very low cut off so hopefully are not dazzling oncoming drivers. They have an autodip function as well.
I think the ACC is a superb piece of tech, the internal lighting upgrades, the 3 section flat surface and the headlights. These are the main improvements over our T5 when we changed.
There will be a lot more people who have them now, so perhaps put the question on a thread. LED headlights - are they that much better?
One other thing, order the 4 sets of keys as well. They are well under £100 if ordered before delivery. Each set is well over that if ordered after purchase.
You will have a superb vehicle which will bring you a lot of fun and great memories.
