As usual, an extremely good write up!

My car has xenon plus, and to be honest I'm slightly disapointed in the full beam, with it appearing a bit weak, and a bit yellow (even with the fancy philips h7 bulbs which are very bluey White to back up the xenons).

Is there any adjustment on them? As I think thwley might be a bit low, or a way to check the self leveling. If there is adjustment I will get a local garage to set them.

I think there is just the usual adjustments on the lights to factor in the position they are bolted into the car - If they were off allignment, it should be picked up on an MOT I would expect, but a regular garage should be able to check them I would think....

Just swapped my standard Xenons for Xenon plus lights today and my ballasts on the old headlights were on side of the headlight just like the Xenon Pluses, perhaps they moved the ballasts over after a certain year and the location of the ballast was not dependent on weather they were Plus or non plus...?

Excellent writeup-nice detail...

Wow these lights are stunning, I've admired them for years. Would love to fit a set someday...
