I just replaced the bulbs in my impreza with osram nightbreakers and the difference awesome best £20 i've spent on the car can actually see at night now! Will definitly be fitting these to the blade!
I fitted Osram nightbreakers on the duke and the difference was amazing. havent fitted them to the blade yet...but then I havent been riding at night yet as work seems to keep getting in the way so far.
reading a few tests on the osram nightbreakers vs philips x-tremeVision seems the osram are brighter in the H4 group test but in the H7 test the philips won.Auto express named them H7 of the year so I might try the x-tremeVision this time round.
