ok first off 3000k (yellow) is the brightest bulb temperature you can get. but they are illegal. another way to make your headlights brighter is to remove the lense and take out the metal thing that surounds the bulb, sorry cant remember the name of the part right now but it looks like you have already done that with those pics you posted. also one other thing you can do its called super charging your ballast i saw a video about it on youtube here is the link. Supercharging a Xentec HID ballast - YouTube but i think it only works with xentec ballasts and dont know how long they will last if you do this.
