I'm trying to get a set of HID's from DDM Tuning (better than VVME?) and I'm not sure what i'm supposed to get here... They will be on GT headlights and Cobra foglights. Is there anything I have to do special for the cobra fogs? I would like them to be a blueish tint, is that 6k? I pretty much just don't know what the wattage numbers, HID harness and error eliminator mean.
