Great!! Really happy for you!
I know how hard it can be having had a seemingly insoluble problem with the wife's Pluriel's dipping headlight, this has now been followed by someone having nicked her left side rear reflector.
I even went to a Citroen garage to ask if they sold bits for cars. The wimmins asked me how old the car was, before I could tell her she said "If it is over 10 years old we won't have them." So I asked if that meant that all Citroens died at 10 years of age. She sympathised and tried to be helpful, she sent me to Aldi!!
WTF?
And Leclerc Auto had all sorts of reflectors but none even approaching them. They (or copies) are made in China but you cannot buy them from France.
If I can find ont internet ones that are remotely the right size and shape I'll get one and, using bits of wood, stick it in place. It is recessed of course.
How did you manage to find them if you don't mind telling us?
