Hi,
I managed to sort out the problem yesterday. I had to swap the wires over in the bulb holder. I didn't do this exactly because I would have had to disassemble the headlight assembly. I actually took out the other part of the bulb holder (where the bulb sits) and I put wires on the metal contact points, put tape over them, then wrap the wire around so the end of it is on top the contact point on the other side.
