This is to replace the cracked/broken/missing plastic trim that goes around the rear reflector housing on the higher-spec DS range, such as the Pallas.
The original Citroen part number was DS 579-93
This is not the same as you can buy elsewhere: We have seen various products being sold for this purpose, of varying qualities. They all have one thing in common: They are all plastic. Ours is not.
This is a MirrorCool product, made from the same specification flexible material that is used for our Dyane/Ami/PL17 headlamp bezel surrounds and our famous MirrorCool door mirror surround trims.
It has been made to match the original light grey, but unlike the original plastic, it is not affected by sunlight and so will remain flexible and strong, and will not shrink or crack.
Sold as a pair.
