Well when you say bulb, I assumed you just wanted a straight bulb replacement, not an LED kit. The GP Thunder get rid of the yellow for sure. An LED setup will go even more white. All that being said though, you WILL NOT achieve the LCI LED look on your M3 with any of the kits available. They will be white, but they won't be anywhere near as bright. You'd either have to go HID for increased brightness, especially in the daytime or a full led ring replacement.
