Well, thanks to all the good advice from members on her, I finally changed the headlamp bulb this afternoon. I did remove a clamp holding part of the wiring harness enabling me to move it out of the way. I found pushing the top of the retaining clip forward and to the left at the same time, impossible so I cut a small notch in the end of a length of 10mm dowel and used this to unclip the spring clip. The bulb change was easy and the clip easy to replace. I did have problems with the plastic cover though. I dropped it and it fell down into the inner wing...I could see it but couldnt get may hand in far in to retrieve it. My wife rescued it but then I dropped it again. This time it disappeared and, at first I thought it may have gone actually into the bumper itself. However, I found it under the car and it was eventually refitted. Job done... many thanks again for the help. Just been out for a drive looking for a location to shoot some pics but unfortunately we've had torrential rain here. Next job is to find out why the fog lamps aren't working. Bumble
