My 2012 HymerExsis has 2 small cracks in the red part of the right hand side back lights. I have been told that as long as no white light is visible it will not fail its MOT, just an advisory but I am concerned it may get worse so if possibleI would like to replace the plastic lens. I cannot see any part number on the lens and I wondered if any funsters have any information that might help me source a replacement lens or light unit
, new or second hand
