I have done a few tests on various LED eBay specials when working on a project and unfortunately they rarely don't throw up a bulb out error. The ones that, when I checked them, worked used a resistor that ran so hot I didn't want it in a confined space but all eBay specials burnt out really quick in my experience. Bite the bullet and buy good quality ones if you want LEDs - they will pay for themselfs cause they will outlast the others by some margin so cost less in the long run.
