Without wishing to go too much off topic I just wanted to say that I'm (so far) very impressed with the new Phillips lamps - they are truly whiter. Autobulbs-direct also provided a set of 'whiter' complimentary side lights free of charge and even though they look deep blue are beautifully white when illuminated - see attached (old on the left, new lamps on the right).
To compare, I fitted both H4 headlamp and side lamp to one half of the car and the difference is amazing - the previous Osram's look seriously yellow and I didn't even notice how bad they were. OK, so they're not HID quality but they are significantly whiter and they do what packet says!
Just one last point, even though mine were on the 'boy racer' Xmas list (with the blue tipped quartz glass) the final effect is a splash of blue at certain angles (quite minimal) and a truly white look.
I did try and take a couple of photos to show the comparison but my camera didn't do the difference any justice
On the whole I can thoroughly recommend the Philip's & white side lamp range.
Cheers
