Just spoke to a very understanding guy from vicroads about the legality of all this. Basically he said, that if a lens has some sort of rating on it like e approval then its very likely that it will be fine for ADR. What he said though is that there can't be any guarantee unless you contact the manufacturer and get it in writing from them that it would pass ADR requirements. He also said that its very likely that they would know if it did or didn't.
It was a breath of fresh air to have someone that was so helpful and understanding from Vicroads, this shows the system isn't 100% broke. He even laughed when i told him that the ADR redirects you to VSI10 regarding indicators, but VSI10 isn't anywhere to be found! Even he couldn't find it!
So, I'll do i little more poking and prodding around and let you all know!
