DDM HID 35w 5000k H11 slim ballast:
This kit lasted for 60,000 miles before one of the ballasts failed. I did NOT use a relay harness. My headlights are always on when I drive. The kit is probably around 2 years old and I don't remember having any issues with the order at the time.
I just ordered a replacement kit (35w 6000k H11 slim) today and I will update this thread with the results.
