I just recieved my 9006 techone hid conversion kit. I went to test them on my car and wired them up to the stock 9004 harness to test them. The first bulb and ballast worked fine. The second only turned on for a split second and shuts back off. I switched the ballasts to see if it was a problem with the ballast or bulb and the other bulb worked fine when I hooked up the other ballast. So I guess it must be a problem with the ballast. BTW the ballast and ignitor are in the same unit for those who aren't familiar with this system. Anyone else have this problem? Am I doing something wrong? I contacted the seller and he told me to ship the ballast back to him but they want $98 to ship it back to him within 2-3 days since he's in china so there is no way in hell thats happening.
