Update:
Both the ballast and bulb were found to be working. My dad had just assumed the HID bulb had died and took it out rather than check the connections. While doing that he cracked the ceramic insulator, but it seems to work just fine. I'm always trying to implement new technology on my vehicles when something breaks, and my dad is always rushing out to buy the old part at full price before I get a chance to try it my way (bought 2 Pb batteries for the truck before I could put in my supercap, bought halogen bulbs before I could diagnose HID, bought a Pb battery for the Acura before I could experiment with a LiFePO4).
Anyhow, I bought H11 LED bulbs from Amazon, and the light output was just slightly less than my HID, but the real problem was the mounting tabs were impossibly fragile and all broke off immediately. Also, the beam pattern in the projector lens was unacceptable. I sent them back.
That said, I tried the same LED bulbs in H7 formfactor for my motorcycle in a reflector housing, and the beam pattern is good and light output much better than halogen. I ripped out the HID kit on the bike and will try the LEDs out.
The best part, power consumption is much less than advertised. I measured 15 watts, and they are rated to draw 25 watts each. That's 1/3rd of the power consumed by the old HIDs.
Here's what I bought:

I wanted a passive cooled LED since fans are susceptible to failure, and I don't want the noise on my motorcycle.
