Product Introduction
The WG9719720001 headlamp L for HOWO 371 is a front left-side headlight assembly designed for SINOTRUK heavy-duty trucks. It is installed on the driver side of the cabin front and plays a critical role in ensuring safe driving visibility during night operations and low-light conditions.
This headlamp provides strong and stable illumination, helping drivers clearly see road conditions in long-distance transport, mining, and construction environments.
Manufactured with high-strength ABS housing and a durable polycarbonate lens, the unit offers excellent resistance to impact, vibration, dust, and water intrusion. It maintains stable lighting performance even under harsh working conditions.
OEM-standard production ensures precise fitment with HOWO 371 cabin mounting points, stable electrical connection, and easy installation without modification. It is compatible with standard halogen lighting systems widely used in HOWO trucks.
Each unit is tested for beam accuracy, sealing performance, vibration resistance, and electrical stability before shipment.
