I had just recently bought a new pair of Halo HID projector headlights off ebay. The Bulbs in the headlights are 8000k. I was told i need to have a relay harness installed in order to improve the life of my bulbs and to remove the "flicker". I dont know exactly what relay i need because i see there is more than one. Im new to the forum and am not sure where to go from here. Also is there anything more that the relay does other than remove the flicker and bulb life? Any help would be greatly appreciated. The link at the bottom is the set i bought.
