I have done a little write up, maybe can be used in the WIKI section if needed.
Firstly, this will only work on Bosch "Bulleyes" and "Smilie" headlights.
This can be done with the lights still on the car, so no need to remove them, but I have done this show it shows you what is needed to be done.
Firstly, looking at the rear of the unit, you will see 3 screws.
You can see 3 plastic tabs sticking up, where these are, I have marked with a black marker pen to show the origional starting point.
These will need to be unscrewed to a point where they will come out from the bottom of the unit, and no more, but will spin into the rear of the unit.
Lift the housing, as shown, and turn clockwise or anti-clockwise, thus making them RHD or LHD, whichever you want to convert too.
As you can see, the Black mark has now moved from the origional mark.
Congradulations, you have now converted the lights.
All that is need is to tighen the screws and refit to the car.
