the bulbs will be 9006 L 9005 H... the assembly comes with the bulbs already, and all you will have to do is plug and play, you could do HIDs but they might have problems with melting the housing bcuz the bulb is too close, just wait and dont buy them off of andysautosport... they werent supposed to put them out yet and if you buy them off of clubgp you get a discount anyway
