1. Remove headlights and take them apart
2. Fit RHD xenon projectors (with halo rings, what you're after)
3. Wire it all up
4. Assemble and re-fit
If you fit some good projectors in (google "TRS"), you'll usually get a better product than some el-cheapo crap off ebay.
The V36 should come with HID from factory, so what you'd ideall want is to just fit the halo rings, wire them up to parkers and put everything back together, nice and easy .
