Maybe i confuse your saying.I'm sorry.Let's make a plan.If i put my bike in front of a wall i see this:
/-------
/
------/
so the light dip to the left!
But i think in AU if you put a bike in front of a wall you must see this:
------\
\
\
--------
and here the light dip to the right.
I hope you understand the plan.Maybe it's the opposite meaning of your saying and you are correct.My english are not very good so i'm sorry.
