HEADLAMP

When the headlamp washer pump is activated, pressure builds within the high pressure hoses to each headlamp washer nozzle. Driven by this pressure, the nozzle is first extended telescopically against the pressure of an internal return spring to its cleaning position below and in front of each front lamp unit. After both nozzles are fully extended, further pressure builds within the hydraulic body of the nozzle, which opens a control valve allowing a precisely metered quantity of washer fluid to be sprayed in several high pressure streams against the lenses of both front lamp units.

When the pressure within the hydraulic body of the nozzle drops, the return spring pressure within the nozzle causes the telescoping section of the nozzle to retract into its relaxed position within the nozzle hydraulic body.
