I replace my main beam H7's with Phillips blue vision ultra, they only give about 30% more light than standard, but give a great bright white light, by far the best ive seen, if its the look your after rather than light output. You also get free blue vision sidelight bulbs which are alot whiter than the standard ones.
I emailed OSRAM about an upgraded H15 high beam/DRL bulb but they have no plans to make one, so i have turned off my DRL's cant stand the yellow ligth,
The better output H7 light bulbs still look abit yellow to me, whereas the phillips i brought are made to look xenon effect
