Yeh thanks, i fitted the new bulbs and they are H7's, access was a bit tight, i needed to undo the bolts for the expansion bottle and move it out of they way to gain access on the offside light and undo the battery clamp and shift the battery over to gain access to the nearside light, a bit of a pain but still a whole lot easier than my Megane where i had to remove the bumper!!!
Let me know how you get on with the xenon's, i bought philips blue vision bulbs as this was what Auto express recommended but although brighter not really the look of xenons i was after.
Guys try the new Philips X-Treme Power H7 (80% brighter claimed). They DO make a difference and they are white, double the price of +30/+50 but bro says well worth the money. Brother just put them in his Merc as a cheap option to Xenons and he's well chuffed he's saved himself over £200.
