Guys, I own a C3 2002 Model, after some nightmares with the front right main beam I managed to solve the spring problem by using a mirror. I only used it once, since than I know what I'm looking for and since I nearly change it once a year!! it only takes me 10min to change. The most important thing is to seal the cover properly after you change it or else you get condensation and thats it!!! Last week I had to change the main beam twice. I had a new faulty bulb, now I discovered I have one of the rear number plates blubs faulty. I never changed it and I cant manage too. Can anyone help me and explain to me from where I can take off the cover or tricks of the trade to change the bulb? Thanks Mauro
