An item of myth and legend, I am now the owner of a Hurst LWB pantograpgh kit! Ok I need another two but at least im a 1/3 of the way there.
Having only ever heard of them and having talked to Andrew Hurst about them, the other nights quick perusal of his site showed one as being in stock.
The other parts being the door opening lights with a 325 they are located in the place of a door open warning, but as I understand they contain a blue shade, they are part of a system to see if anyone is in the coach.
