Complete Kit to install the legally required screen washers. The kit includes  Washer Bag and electric pump, 12v connecting leads and plug, Retractive switch c/w bracket, two double Washer Nozzles, Clear plastic water pipe, Through and T pipe connector, pipe clips, mounting plate and fixings screws. Originally Isetta's did not come with a screen wash system but sometime around 1970 a respective law was brought in requiring a screen wash stystem to all vehicles. My suggestion is to install the mounting plate to the original two holes already on the back of the Dash Board or do what I did and make two wire clips made  from something Coat hanger wire as you will find it much easier to remove bag when filling with Screen Wash Note The Nozzles included in this kit may not be in keeping with the period and you may want to fit a classic chrome Nozzle
