Headlights problems
 

Hi after passenger side headlight wouldn't come on bought new xenon bulbs removed air box and other stuff for access and removed bulb connected to its ballast starter the new one is different shape it's square and now it still won't work is there a separate ballast connected to the underside of headlight or have I just got wrong build and connector thanks kev

The bulb on the right is the same as fitted to my S60. D1s. Bulb on the left I have no idea. Take the rubber cover off the headlight that is working and take a picture of the bulb fitted there. That will tell you which model of replacement bulb you need.
