Just got a set (only 2) of Osram Night Breaker lights (they are delivered from Ossett in West Yorks, my home town!) and I fitted 1 of the free Phillips blue Vision W5W bulbs. They are blue in colour but do not light up blue! One other thing..... why do VW put great bulb holders in the indicator and main head light but sh!tty impossible to get out ones in the side lamp and main beam? Hand are cut to bits trying to get the small side light bulbs out 
See my post on the previous page.

Thats what I fitted and thats where I got them from.
