I just got may HID kit in the mail from DDM tuning. I hooked them up to make sure they work before I do my retrofit. I found that when I tested them without the relay harness everything is all good. When I test it out with the relay harness I get a buzzing sound. It's not loud and it only last for about 20 seconds. I'm not sure about this buzzing sound. Is this normal with HIDs?
