He he...
I just swapped mine and my girlfriend's Punto dipped headlights for new bulbs (top kit by the way!!! I'll detail more below).
On my girlfriend's car (2001 without integrated foglights), I EVENTUALLY got the cover off the passenger side. Total pain though and my fingers hurt now.
On my passenger side though, (2003 Active Sport with foglights), my god did I do some swearing.
In the end it was the easy option to undo the three bolts holding the headlight unit to the car. That allowed enough forward movement to get the cover out of the way and remove/replace the bulb.
Obviously you need to make sure the unit goes back into the same place but the clean bits under the plastic mounting showed me where to put it back!!!
As for the bulbs, well....
Got them from
www.powerbulbs.co.uk
TOP TOP TOP service. Not only were the prices good (incl. free delivery) but they got here next day (and I'm in Scotland now).
Got a set of the Philips 150's (H7 fitting) and the Osram Cool Blue (H1 fitting, and CHECK your lights for which bulb you need. The Punto 99-03 has H7 fittings according to everyone everywhere. I can assure you that the dipped and main bulbs on mine are BOTH H1 fittings).
Plus at the moment you will get a set of the Philips 'blue' sidelights free. So I now have a seriously nice looking white beam rather than the more yellowey colour. And note that eventhough the Osram and Philips bulbs are 'blue', they aren't just to give a stupid blue effect, these are top bulbs.
Sorry about the long post!!!
