Hey guys, within the last two years I had to replace my OEM bi-xenon ballast 4 times.
Bulbs are all oem and work fine when switched with the drivers side.
Generally the ballasts last for about 3-4 months then dies out of nowhere.

Connections are all solid and harnesses look fine. I'm at a loss for options now and wonder if you guys had any insight on the core problem?

thanks
