ACDelco 23110567 Front Driver Side Headlight Leveling Position Sensor

The ACDelco 23110567 is a genuine GM headlight leveling position sensor designed for the front driver side. This sensor is a critical component of automatic headlight leveling systems, which adjust headlight beam angle based on vehicle load and road conditions to optimize visibility and prevent blinding oncoming traffic.

Key Features:

• Genuine ACDelco OE replacement part ensuring factory fit and function
• Front driver side (left) mounting position
• Works with automatic headlight leveling systems to monitor suspension height
• Durable construction designed to withstand underbody environmental conditions
• Direct replacement for worn or failed factory sensors

This sensor assembly mounts to the front suspension and communicates vehicle ride height information to the headlight leveling control module. When the sensor detects changes in vehicle stance due to cargo load or road surface angle, the system automatically adjusts headlight aim to maintain proper beam pattern. Replacing a faulty headlight leveling sensor restores proper automatic headlight adjustment and may resolve dashboard warning lights related to the leveling system.
