811W25320-6003 Front Combination Lamp Assembly

The Front Combination Lamp Assembly 811W25320-6003 is a specialized left-front combination lamp unit designed for the Sinotruk SITRAK C7H vehicle. As the core component of the vehicle's front lighting system, it serves multiple critical functions.

Product Function

1.Core Lighting Functions
This assembly integrates various lighting functions, including a combined front fog lamp and turn signal design, providing comprehensive illumination for the vehicle. It effectively lights up the road ahead during nighttime or low-light conditions, ensuring clear visibility for the driver and enhancing driving safety.

2.Signaling Functions
Beyond basic illumination, the assembly provides positioning, signaling, and turn indication. The turn signals clearly communicate the vehicle's intended direction to other road users, while the position lamps outline the vehicle's轮廓, improving its visibility in low-light environments.

3.Adjustment Capabilities
Some advanced versions of this assembly feature vertical adjustment functionality. Working in coordination with vehicle height sensors and the control unit, it can automatically adjust the vertical beam angle based on driving conditions, further improving nighttime safety.

Main Purpose

1.Ensuring Safe Vehicle Operation
The primary purpose of the assembly is to ensure safe vehicle operation under various lighting conditions. By providing adequate illumination and clear signals, it allows the driver to maintain clear visibility during night, fog, and other adverse conditions, while ensuring the vehicle's position and intentions are recognized by others.

2.Specialized Design for Commercial Vehicles
Designed specifically for medium and heavy-duty trucks, the assembly addresses characteristics like higher power output and heat dissipation needs. It employs a design that separates functions to manage heat generation effectively, reduces the rear volume of the lamp unit, and solves space constraints in the front assembly area.

3.Ease of Maintenance
The design prioritizes maintenance convenience. A pivot mechanism allows the lamp to be swung forward from the rear, enabling bulb replacement and connector servicing from the front of the vehicle, significantly improving maintenance efficiency.
