Yep - swapped might to Phillips Bluevision. Very good, much brighter and whiter than the ones that were in there (which were Osram 50% brighter bulbs, which I only discovered when I swapped them out!).
I've actually just recently put in some cheapo bluevision copies I got for about £3 from Lidl a few years ago, and although the light has a slight green tinge they're really not bad.
Gotta admit though, it doesnt make much difference to me as I have the extra two driving lights in my bumper that come on with my highbeams, which is when you notice the lack of headlight light most. In fact they're so bright I didn't realise I had a headlight bulb out until a friend told me
