Swapping Ballasts? (need Help Asap!)

[phatrabbitzz]

I have an HID conversion kit that came off of a Lexus 2002. It seems as if one of the ballasts is causing a shortage in the circuit.

Here is a pic of the "bad" ballast:

Questions:

1) Can I use a different ballast and still let it work with the same bulb?

2) If so, how would I know that the bulb that came with that ballast will fit in the new ballast?

TIA
