Note
To replace the headlight bulbs, there is no need
to disconnect the main wiring harness from the
headlight bulb holder.
Note
Be careful to hold the new bulb at the base only.
Never touch the transparent body with your fingers
or it will blacken resulting in reduced bulb brilliancy.
Refitting
After changing the burnt-out bulb, replace the cover
and close it by pressing it against the lever.
