I've just spoken with the Technical Department for Vehicle Examinations in Welshpool and have been advised that:
1. Changing Halogen to Xenon is acceptable, only if the Xenon kit complies with ADR (Australian Design Regulations)
2. They will not supply that in writing, because if the product complies WITH ADR, there is no need for you have it in writing.
It was recommended that I contact places like Hella etc, who make Xenon kits and to discuss with them the situation, and because they are fully aware of the ADRs, they should be able to provide me with any further information.
Later today I will contact Hella and possible Bosch, Panasonic and Phillips (all of whom I have seen have some part to play in the creation of Xenon kits, be it the Ballast or the Ignitor systems) and see what I can find out.
Hicks, not all of us have disposable income to go out and purchase things we want/need at a drop of a hat. Xenon lights up the road so much better than Halogen lights, and as I enjoy night cruising, I feel that is it something that *I* need.
