| As has been mentioned before the springs holding the bulbs in can lose their tension allowing the bulb to wobble or even point in the wrong direction.
I've also seen bulbs installed upside down which will also adjust the filament's position in relation to the reflector & threfore throw the beam way out of line.
As for adjustment...
Headlamps up to 2003
Adjuster on LHS ( near to fuses) clockwise adjusts down, anticlockwise up
Adjuster on RHS ( near to coolant header ) clockwise adjusts right, anticlockwise adjusts right.
Is it a UK headlamp?? look on the LHS of the lens as you see it, there are 2 E3 markings... at the lower part of the lens... the one towards the centre of the lens has an arrow pointing in the direction the dip beam goes... UK should point to the right as you look at the lens.
( To alter the dip if it's non UK remove the dip bulb & inside the lamp is a small plate held in with a screw... this defines the cut off for the dip. Get chopping & bending... ) It's much easier to get out if the headlamp is removed which doesn't take too long once the fairing is off.
Have you actually set your headlamp to the standard setting fiirst???
As per the manual, with the headlamp 10m from a wall, the top of the horizontal cutoff of the dipped beam pattern thrown onto the wall should be about 90% of the height of the centre of the headlamp from the floor... this could be an easy starting point.  |
