Sinotruk HOWO truck spare parts T7H Combined Headlight Assembly (electric modulation +DRL) left head lamp WG9925720061 0062

Introduction of the combined headlight assembly (electric adjustment + DRL) left headlight WG9925720061/0062

Functional features

Lighting function: The bulb or LED light source inside it can emit bright light to illuminate the road in front of the vehicle, allowing the driver to clearly observe the road conditions under low visibility conditions such as night and rainy and foggy weather to ensure driving safety.
Electric adjustment function: The height adjustment and steering adjustment of the headlights are achieved through the horizontal position sensor and steering angle sensor installed on the vehicle. When the vehicle is driving on different road conditions or carrying items of different weights, the driver can automatically or manually adjust the illumination angle of the headlights through the adjustment switch in the car to obtain the best lighting effect, illuminate the blind spots of vision, and improve driving safety and comfort.
Daytime running light function: The daytime running light (DRL) automatically lights up when the vehicle is started, emitting soft and eye-catching light, improving the recognition of the vehicle when driving during the day, making it easier for other road users to notice the existence of the vehicle, and helping to prevent traffic accidents.

Working principle of the combined headlight assembly (electric adjustment + DRL) left headlight WG9925720061/0062

Electric adjustment principle: When the driver operates the electric adjustment switch, the resistance change inside the switch triggers the internal circuit system of the electric adjustment regulator. The regulator drives the DC motor to execute the command according to the direction set by the switch. The high-speed rotation of the motor is transformed into low-speed linear motion through the fine transmission of the gears inside the regulator and the clever transformation of the spiral mechanism, thereby accurately adjusting the inclination angle of the headlight and achieving fine adjustment of the light angle.
Working principle of daytime running lights: Daytime running lights are usually connected to the vehicle's power system. When the vehicle is started, the power is turned on, and the control module in the daytime running light circuit will automatically control the opening and closing of the daytime running lights according to the preset program and sensor signals. In general, the brightness of the daytime running lights will be automatically adjusted according to the intensity of the external light to ensure good visibility under different lighting conditions without causing dazzling interference to other drivers.
