My beam pattern is similar and i have H7 bulbs.
Thanks. So you have the same shadow-stripes?
If so, it must be the ground return wire on the bulbs. It's in the wrong location.
Maybe we can do the ' 6 o'clock mod '?:
Example with a plastic socket (I have a steel socket)
the random black spots are caused by the ceramic hid earth connection that runs down the side of the hid bulb
the 6 oclock mod basically adjusts how the bulb sits in the headlight by rotating it moving the black spot somewhere else.
you will have to look where to make the new tab as it may be different in your lights
