    Ive noticed that my dip beam headlights dont seem to light up the road much more than a few metres ahead and im sure they never used to be that bad.

    I have halogen lights not xenon, and the lights do a self levelling thing when you first turn them on which seems to be working ok.

    Im just wondering if this car has a headlight self levelling sensor and if so where abouts is it?

    Ive adjusted the little wheel on the dashboard so they are on the highest possible position but they still seem very low. Full beam is absolutely fine its just dip beam.

    Any suggestions?

    Thanks.

    They won't be self leveling if you don't have xenons. The motors, controlled by the little wheel, do a test when you turn on the ignition and you can see the lights go up and down.
    You can still adjust them manually though one screw hole on top of the light unit for up and down and another screw hole for side to side.

    If you have a hieght adjustment knob next to the light switch, you dont have self levelling. The hieght adjustment is the centre "wiggly knob", and the lateral adjustment is at the outer end. To adjust the lights, put the car 25 ft from a wall and draw a horizontal line at the hieght of the dip beam light centre, and mark the distance between them. The cut off should be 5cm lower than the line, and the "kink" at the mark. ( Theres a thread showing headlight adjustment with a diagram, but I cant remember where it is !)

    Cheers for your help guys i adjusted them myself in the end and they are far better than before! It was dangerous before tbh must have been caused by lowering the car i guess.
