This Headlight Level Sensor is a replacement electronic sensor engineered to replicate the original Porsche ride height/level sensing component used in the headlight levelling system. It is designed for direct installation in compatible Porsche 911 (991), Boxster (982) and Cayman (982) models to work with automatic headlight levelling systems.
Fits:
Porsche 718 Boxster - 2017 Onwards
Porsche 718 Cayman - 2017 Onwards
Porsche 991.1 / 991.2 - 2012 to 2019
Porsche 991 turbo - 2017 to 2020
Diagram ref no 17
The headlight level sensor detects changes in the vehicle’s suspension height and sends accurate position data to the headlight control module. This enables the automatic headlight levelling function, allowing the headlights to adjust their beam angle based on load and vehicle pitch - helping maintain optimal illumination and preventing glare to other road users.
Mounted to the front suspension/ride height linkage, the sensor reads positional changes and converts them into electronic signals. The control module uses this data to raise or lower the headlight beam dynamically, ensuring consistent light alignment regardless of load, acceleration, or inclination. It supports safer night driving by keeping beams properly aligned.
A faulty headlight level sensor can lead to inconsistent beam aim, poor night visibility, dashboard warnings, or disabled levelling functions. Replacing a worn or failed sensor restores correct feedback to the headlight control system, maintaining proper beam alignment and ensuring safe, predictable nighttime lighting performance.
When to replace:
• Headlights won’t auto-adjust when load changes
• Levelling warning or fault codes on the instrument cluster
• Beam angle appears too high or low under load
• After suspension work / sensor linkage removal
• As preventive maintenance when replacing related sensors or heads
