Further investigation suggests the Australian version has a reversing light low down to replace the fog light (no fog in Australia?), with a second brake light on pedestal just in front of filler cap.
Perhaps someone with the Oz version can confirm this and explain what if anything the far left switch (fog light in UK versions) does.
What I'm aiming for is a reversing light in pod (same as indicator) mounted on top of double rear light, although may then reverse locations and place fog light in this higher position. I need therefore to find source of pod and white LED light - any suggestions other than MMC?
