Help appreciated regarding this matter.

I have a 2011 c204 which has had a few mods to say the least.
Some how the passenger side headlight steamed up inside and the headlight stopped working.
After a diagnostic check it appears the ballast is dead.
It is prooving very difficult to source a used or aftermarket one.
I have looked at generic ones which seem like the could be ok however the car has the intelligent lighting system.

Has any body had this issue and found a suitable solution?
Or can anyone provide any advice?

Thanks in advance
