Hi

My E46 has factory fitted xenon lights and the passenger side light has been flickering lately. If I switch off the lights and then switch them back on, the flickering stops for a few minutes. It seems to be a common problem with the ballast so I'll replace it once I have confirmed that it is causing the lights to flicker.

My question is, where is the best place to source a new ballast? Are the spurious versions on eBay just rubbish?

Thanks
Brian
