We purchased virtually all of our LEDs from Ebay nearly 5 years ago when we did our conversion to LEDs. A quick look at Ebay (G4 2-pin base) showed many options available, maybe one of them would work and they are cheap to try. All of the LEDs we purchased from an Ebay store recommended by a RV.net forum member many years ago are still functioning fine, the few we purchased here in the USA have all died and have since been replaced. Hope you are able to find what you need, we used mostly flat panel LEDs without voltage regulators and although our converter charges at 14.8 Vdc, not a single LED on any of the arrays has burnt out.
