ProParts 32-019-890 Front Headlight Level Sensor for Xenon HID Systems

The ProParts 32-019-890 is a front headlight level sensor designed for vehicles equipped with xenon or HID (High Intensity Discharge) headlight systems. This sensor plays a critical role in the automatic headlight leveling system, continuously monitoring the front suspension position to ensure proper headlight aim under all driving conditions.

How It Works:

Mounted to the front suspension components, this sensor detects changes in vehicle ride height and pitch angle. When the vehicle's load changes or when driving over uneven terrain, the sensor sends data to the headlight leveling control module, which automatically adjusts the headlight beam angle to maintain proper illumination without blinding oncoming traffic.

Key Features:

• Direct replacement for OEM part number 28343353
• Essential component for vehicles with xenon headlight systems
• Monitors front suspension deflection and ride height changes
• Provides continuous feedback to headlight leveling control module
• Prevents headlight misalignment due to vehicle loading or pitch changes
• Helps maintain safe illumination while reducing glare to other drivers

Important Notes:

This front sensor typically works in conjunction with a rear sensor to provide complete vehicle pitch monitoring. Most automatic headlight leveling systems require both sensors to function properly. When replacing a failed sensor, proper calibration using diagnostic equipment may be required to ensure optimal headlight performance.
