How to adjust / aim Volvo Xc90 bi-xenon HID headlights
The HID headlights on my girlfriends Volvo xc90 r-design needed to be aimed higher so the Bi-Xenon headlights would produce a better throw onto the road. You need a 6mm socket to adjust the Volvo headlamps up by turning the white points counterclockwise. These new volvo headlights work very well now.
