i have SEAT 50% Xenon plus main beams - from SEAT dealers and cheap
My full beams are Osram night breakers
Both sets were less than £20 and both very good. I've had the SEAT bulbs for about 4 years and they've been in my last 3 cars - they are that good !!
Bought the osrams when I got BMW back in August.
They both have a very white/blue light
