Product Description:

Auto headlamp control unit
OE number: 30784923
Applicable vehicle type: For Volvo

The headlight module serves as a pivotal component within the vehicle's lighting system, functioning as the “intelligent brain” of the illumination system.

By receiving signals from various sensors including the vehicle height sensor, speed sensor, and ambient light sensor, the headlight module processes this data through its internal microprocessor. It then issues commands to the headlight control circuitry or actuators based on pre-programmed algorithms, thereby enabling diverse control functions for the headlights.

Functional Features

• Headlight Switch Control: When the driver operates the headlight switch, the generated signal is transmitted to the headlight module. After analysis and processing, the module issues commands to precisely illuminate or extinguish the headlights.
• Automatic Headlight Control: An integrated light-sensing system detects ambient light intensity. Headlights activate automatically when light levels diminish and deactivate when they increase. The system also automatically adjusts headlight brightness according to ambient light conditions.
• Beam Angle Adjustment: By receiving inputs from the vehicle height sensor and speed signal, the module processes this data to drive the headlight angle control motor. It adjusts the headlight beam angle based on vehicle load and speed, ensuring optimal illumination performance.
