I'm hunting for x2 lamps the same as these has anyone seen them?

As far as I know Classic Boat Supplies would be your best bet in Australia (Terry Hills NSW; shop.classic-boat-supplies.com.au/ I've used them only once but they were good) but I can't see anything matching your lights on their web site. Maybe give them a ring? Anglesey Marine Supplies seems a lot cheaper- presumably because of the bigger UK market.
