Wait does this mean I just pull out my old bulbs and put the new XENON 5000K in? Or is there still something I'm missing? you replaces your standard halogen globe with the new xenon globe and the ballast simply plugs into the original plug for the headlight loom. if you purchase a kit it will come with easy to follow instructions Thanks :) I feel happy, I don't need to pay for installation, it sounds so DAMN easy :) so how did u got with it mate? im thinking to change mine too but still havent got the time to search for the right HID lights.. what are u getting btw? D35 hey i changed my headlights to xenon 6000k and da light bulb size should say on da headlight unit HB3 for hi beam and for da low beam is HB4
