Xc60 xenon lights and led upgrade

[Aussiexc60]

Hi

I have an XC60 2012 R design d5 in Australia with Bi Xenon lights with active bending but don't think active dimming for oncoming traffic.

From the centre of the car in the headlight is first a halogen globe, then next the xenon globe with lens, up and out from that is the little orange globe.

A Few questions

1 The inner Halogen, what is this called?? It comes on when lights are on what we call "HIGH BEAM" or when "flashing" lights. Is it the dipped beam H7 LL globe? Though when we dip our lights here that would mean turning off highbeam??!! The manual shows removal of the headlight assembly on the port side LHS of the car....then shows the back of the unit, which seems to show the mainbeam OR ABL Extra Main Beam on the inside side, as in furtherest away from the direction indicators of side markers. But my ABLs (bixenons??) Are next to the direction indicators?
2 Once we get to the bottom of question above, has anyone successfully changed that halogen globe for an LED without modification of the headlight back cover and no CANBUS errors?
3 Car is now 5 or 6 years old, would there be a noticeable difference if we replaced the xenon globes now, instead of waiting for eventual failure (how long do they last or perform at maximum brightness)
4 When HIGH BEAM is selected, the inner Halogen comes on AND it seems that something moves from in front of the xenon globe so instead of say 50% of the light getting through, it goes to 100% mechanically.
5 I have sometimes had oncoming cars flash me (suggesting I may have been blinding them, even when only on LOW beam. Are these actually adjustable OR do they, as it looks like when starting up do they "self level" every time to adjust for any change in load, so even if I did manage to adjust them, they would just level out next start??
6 If not adjustable, are there any troubleshooting steps to follow or check other than a dealer check?
7 The "pattern" of light that the goes out, is it determined by whatever it is mentioned above that is blocking out the light when on low beam? Is it possible that this has become misaligned and may be causing blinding to oncoming traffic?
