I haven't bought anything yet. I am trying to find out what kits and accessories people have needed to prevent flickering. BOW, and misfires. If it takes getting the relay and harness with capacitor, so be it. I just don't need something to stop working like headlights. I do not want to get pulled because my tint is too dark. Add that and the fact that I have a black on black, my car is dark as anything. What brand kits did you go with? I do want 5000k bulbs for the headlights. I may get the fogs done later on down the road.
