Sounds like the Comms 2000 unit has failed.
This is a known fault and will get worse.
It could result in your other lights starting to have problems.
A replacement is the only answer
Speak to a dealer especially if you are still in warranty and if not ask if they are doing anything about the known problem?
At one stage Peugeot stopped fitting replacements because they just failed the same.
We had 13 fitted under warranty and eventually Peugeot got its act together and produced a more stable product.
Good luck
