:shades:Its all about ADRs so a great site to also check out if you need to know what is needed to get your particular car passed in Aus go to;
www.infrastructure.gov.au/roads/publications/index.aspxYou can down load copies of what is normally required and this is also what the engeneer will check/want changed to make the car to the Australian standards.
The indicators & tailights are not to big a problem if you are good with wiring.
With the front indicators you can open the plastic case & add a divider (about a third of the units size) then add another bulb socket for use as the parker when you split the indicator wiring.
The rear brake/park light will need the indicator wire split and what I did was then wire this into the existing reversing lens and used a Orange bulb for indicators. I then added a new small clear bright bulb (dash bulb size but a halagon) into the housing for my back up lights.
You may be able to get away with just leaving/using the amber indicator bulbs as reverse one also depending on the ADR.
Good luck
