How Headlight Washers Work?

Headlight Washers

A typical headlight washer system consists of a reservoir for water or cleaning fluid, a pump, and nozzles positioned strategically near the headlights. When activated, the pump draws the cleaning solution and propels it through the nozzles, creating a powerful spray that washes away dirt, grime, and debris.

Different types of headlight washer systems exist, like retractable nozzles that pop out and spray before retracting, or stationary nozzles that are always visible and spray when activated.
