the right front xenon light stopped working. I replace the new bulb, it didnt work, check the fuse and find that the problem is probably in the ballast. How to deal with this problem? The bulb inside is a D2R type.

Can the red connector be connected to my old original connector for the xenon bulb? and the 12V wires from the new connector fit to my old connector?

To isolate the ballast problem, have you tried swapping LEFT ballast over to the RIGHT side to determine if the bulb lights up? If it does, that may indicate and confirm that the questionable ballast is faulty.

first I will check the contacts, and then put up the ballast from the Fl model with some modification

If you're sure it's the ballast, just buy a factory one. The connector to the car (not the bulb) will probably be specific and you won't be able to easily connect the aftermarket one. Check ebay or scrap yards in your area if you want to save money by buying a used one (use the part number printed on your bad one so it's an exact fit). This is what I did twice in my C55 years ago.

the factory ones for the pre-Fl model all had these faults which were only fixed with the Fl model
