This is my thread regarding aftermarket head light units and their alignment

Just in case it may
help you in some thing or another.
And this is how my current alignment is:
Or at least that's how they were when I first installed the headlights.. (at the time I had 8000K hid bulbs thinking they were 6000K, basically the seller fooled me and I didn't check the label on the bulbs). As you can see, the kick-up is pretty high, while the alignment itself was low at the time, I have raised it since then so I can get a better view of the road ahead, pavements, etc.
Ever since I raised the lenses using the allen keys, however, the kick-up became even higher and I believe that they are a bit bothersome to people who are on the right lane (while I am in the middle) in front of me, not next to me. It kind of hits them in the left wing mirror, but I have received no complaints so far. I am not sure why companies like Dectane and AutoArt prefer that large kick-up as opposed to lenses in (most) OEM headlights which have a fairly small kick-up.
I am not sure, but I believe the cut-off and kick-up in your headlights are almost exactly the same as in mine, and I know that because there's a user here named Willz who has the same headlights as yours and he was sort of complaining about it. So when you raise the lenses (you probably will) take care of the kick-up or it might bother people or even fail the MOT test. Also although cutting a hole in the rubber cover in order to pass the wires is easy and simple, be careful because the rubber itself is very weak and it may keep tearing and the hole getting larger while you adjust the bulbs or wires or something.
So I was right, go for the plastic bulb base FOR SURE because it doesn't get as hot and you'll be able to touch and adjust the bulb using the plastic part even if it has been on for a while.
