Womala Head Lamp Headlight Washer Nozzle Sprayer OE 1648600547 for Mercedes Benz
The Head Lamp Headlight Washer Nozzle Sprayer (OE: 1648600547) is a core component of the exterior cleaning system for Mercedes Benz W164 series ML models. Mounted on the front bumper (integrated with the headlight washer system), it atomizes and sprays cleaning fluid precisely onto the headlight lenses to remove contaminants. As an OE-grade part, it meets Mercedes Benz’s strict standards for spray precision, corrosion resistance, and durability, ensuring reliable operation across conditions (e.g., dusty roads, insect-prone areas, extreme temperatures).
Constructed from high-performance materials: the nozzle body uses weatherproof and impact-resistant plastic (to withstand road debris and harsh weather), while the internal flow channels are precision-machined for uniform spray distribution. Sealing components prevent fluid leakage, maintaining consistent cleaning efficiency.
Core Functions
- Precision Cleaning: The primary function is to spray cleaning fluid in a targeted, atomized manner, effectively removing dirt, insects, and dust from headlight lenses without scratching the surface.
- Visibility Improvement: Ensures unobstructed headlight illumination, enhancing driving safety during nighttime, low-light, or adverse weather conditions.
- System Compatibility: Works seamlessly with the vehicle’s headlight washer pump and fluid reservoir, delivering timed and pressure-controlled spray for optimal cleaning results.

Notes: This Head Lamp Headlight Washer Nozzle Sprayer is model-specific and designed exclusively for the listed Mercedes Benz W164 series ML models. Do not use it for other models or variants to avoid issues like misaligned spray, weak fluid output, or fitting gaps. During installation, ensure the nozzle is correctly positioned to align with the headlight lenses and that the fluid hoses are tightly connected to prevent leakage. Periodically check the nozzle for clogs (from dried fluid or debris) or cracks, clean it with a soft brush or replace it immediately if faults are found to maintain clear headlight visibility and driving safety.
