| The main beam should point straight ahead. The dip beam can have a straight cut-off (US dip) or can have a cut-off with a rise in the beam to the left (UK) or right (European).
On the ST the dip beam is a projector unit and the beam pattern and dip is done entirely within the projector. Note that headlamp glass on the left side over the projector is entirely plain. The main beam pattern is produced both by the reflector design and the the glass of the headlamp lens.
If the main beam is directed ot the right, either the headlamp adjustment is badly out of alignment (there is a side to side adjustment screw at the right rear of the lamp unit), the bulb isn't seated properly (this is easily done with H1 bulbs) or, the front subframe is bent. |
