Hey Joe-In-Australia, most of the Autobarn chain has a heap of these lights to look at, or at least order. They aren't expensive here, they're on every second rat-trap Gemini...
I looked at them (at the request of the kids) but was talked out of them by the guy in the shop! He just asked, "Will you drive in the rain?" and when I said yes he said there was nothing on the market (even LED) that will stand that on a regular basis. He pointed out in one of the installation manuals that they were 'water resistant' and regular exposure to water junks the warranty!
