Those headlamp bulbs look really blue, i have the Sylvania silverstars and they are much more white. Are you running the cool blues or silverstars or something else? I know you said OSRAM but isnt that just the European name for Sylvania?
they are the osram silverstars. and i would tend to think that they are at least slightly brighter than sylvania only because of the d.o.t. approval. the osram actually have very little tinting to the bulb. i think they just burn a little more white. the fogs really are more yellow than the pic looks. it doesn't quite justify but comes close.
