as far as looks go, it also depends, do you want that super white color, that bluish white color, or the chameleon type lights (y'know they change color depending on where you're viewing them from (they're stock on a lexus but i forget which one)). i personally like the super white ones. the bulbs run you about $80. the bluish one's are nice too, and a lot cheaper at $24. i don't know how much the chameleon one's are, but i don't necessarily like them.
