I don't think the light bulb is faulty. I believe the fault is in the "shutter mechanism" that needs to be coded to the control unit in order to make it work...

I bought a new pair of HID bulbs before realizing the control unit was bad. I can always give it a try and change bulbs if needed, but I'm sticking to coding the control unit.
