Just saw this thread and had to post my contribution. I would avoid the usual "blue-tinged" bulbs as they look horrible in daylight when off as they illuminate the entire light housing and give off the blue colour!
After much deliberation, I settled on these:
Much better than stock BMW Longlife H7's and also look improved visibility. Better than the Philips Blue Vision as well IMO.
No pictures unfortunately, but they're cheap and I would buy again without hesitation. Autoexpress seem to agree as well
I would add, that although they look blue-coloured, the effect is hardly noticeable when off and additionally, the use of Xenon gas makes the biggest difference to their colour and effectiveness. Road-Legal as well.
