The washer nozzle's construction is prepared to work with the factory pump and hoses, and its placement on the right side of the vehicle ensures:

• the correct spray angle relative to the headlight surface,
• proper routing of the fluid hose within the bumper compartment,
• mechanical stability during system operation and high-speed driving.

Its original origin from the Mercedes brand promotes technical consistency with other components of the lighting and windscreen washing systems.

Product Characteristics and Condition

The washer nozzle comes from the vehicle manufacturer's offering, which translates to dimensional compatibility with the factory headlight and bumper.
