I phoned my local Bongo specialists, and they were puzzled that the wing mirror had repeaters in them, they had never seen them and referred me to Bongo Spares. I spoke with a very helpful bloke there who expressed the same opinion - 'never seen them like that' he said.
So I am a bit stuck - has anyone here encountered wing mirrors with repeaters in them, and if so where / how to get them fixed / get a replacement?
