ACDelco Driver Side Headlight Leveling Position Sensor

The ACDelco Driver Side Headlight Leveling Position Sensor (also called a headlamp level sensor or headlight height sensor) is a replacement part for vehicles with automatic headlamp leveling. It detects whether the vehicle is tilted forward or back. The headlamp beam is then adjusted to match, which helps keep visibility good.

Key Features:

• Monitors vehicle pitch and level so the headlamp aim can be corrected automatically
• Helps keep headlights at the proper adjustment height under changing load and suspension conditions
• Designed, engineered and tested to rigorous standards, and backed by General Motors
• Built as a driver side (left) replacement for a factory-original fit and function

Replacing a faulty leveling sensor can restore correct headlamp aim, so you see better at night and oncoming drivers are less likely to be glared. ACDelco is General Motors' parts brand, and its replacement parts are built to GM standards.
