Hello All (again),

Car is to go to dealer soon. I took the attached image. Do you all have the same dark patches in your dipped bi-xenon beams? I think on my car these un-illuminated parts of the beam are giving me the dark patches on the road.

Ignore the right foglight beam in the pic, car had wheels turned to right.

Definitely never seen that before.  I wonder if your bulbs have been replaced (with non-OEM?) and the focal point is now off centre with regard to the projector lens?  Could have been done to change the colour temperature upwards to a bluer one (say 8,000°K instead of 5,300°K)

It's almost as if the arc isn't striking in the correct spot ('Xenons' are arc lights). ???
