Call into your main dealer they should know. if not the AA.or RAC.

You can get headlight protectors from Peugeot for these. They are marked
with the positions of the mask, and include the bits of black plastic too.
However, my 307 has an almost flat top to the dip beam, and although I have
the protectors, I actually have never used them for this purpose. Just make
sure the dip is not too high.
I do drive in France quite a lot. I bought the protectors with the intention
of just using them for masking when in France, save having to keep sticking
bits on the lenses, then having to clean them off when returning.
You can also buy those beam deflectors from places like Halfords, and they
come with lots of diagrams for various cars.

Not sure where it was but I read somewhere that most modern cars dip
vertically rather than diagonally and, therefore, do not need blanking.
Check yours out though to be sure.
