Headlamp washer system

A spraying device for a headlamp or taillight-cleaning system for a motor vehicle comprising

• a housing containing a top and bottom portion defining a chamber therein for fluid ingress and egress into said bottom portion wherein said housing includes an outer structure containing an inner structure, and a tensioning device which releasably positions said outer structure at said housing bottom;
• said inner structure engaged to an arm member for spraying said fluid, such that said inner structure causes said arm member to move in a linear and rotating relationship relative to housing;
• said outer structure and inner structure engaged to one another such that said outer structure causes said inner structure to move in a linear and rotating relationship relative to said housing;
• wherein the ingress of fluid in said chamber causes said inner and outer structure to move linearly and wherein at a predetermined point the inner structure is prevented from moving in said liner direction while said outer structure continues to move linearly, thereby causing said inner structure to rotate.
