ACDelco Headlight Level Sensor

The ACDelco Headlight Level Sensor (also called a headlamp leveling sensor or automatic headlight level sensor) is part of the vehicle's headlight leveling system. It monitors changes in vehicle ride height and body position. It sends that information to the control module, which adjusts the headlight aim. This helps keep the beam pattern properly aimed when the vehicle is loaded, towing, accelerating or braking.

Key Features:

• Helps maintain correct headlight aim as vehicle load and ride height change
• Supports better night visibility and reduces glare for oncoming drivers
• Designed as a replacement for the original equipment sensor
• Backed by ACDelco, a General Motors parts brand with a long history in OE-quality replacement components
• Suited to both vehicle owners and professional technicians

A failing level sensor can cause headlights that sit too high or too low, a headlight leveling warning message, or an inoperative auto-leveling function. Replacing it restores proper headlight aim and the performance of the leveling system. Choose the individual part number that matches your application.
