I bought a new Swift colonsey, it is coming up for it's second annual service. While in France in April was stopped by French Police who checked the caravan ie road lights as I had a defective rear bulb not a problem but they pointed out that the silver paint inside the light casing was pealing off and to get it changed. I then started looking at other Swift caravans of the same year or newer and a few had the same problem. Can you tell me should the Dealer replace these free of charge.
