Porsche Headlight Level Sensor - Genuine Porsche 99134302101

Product Information

A headlight level sensor is a component in a vehicle’s lighting system that detects the vertical position of the vehicle’s headlights. It is part of the automatic headlight leveling system, which adjusts the angle of the headlights based on the vehicle's load and suspension height. This feature helps ensure that headlights illuminate the road properly adjusting based on the height of the vehicle over the road.

• Improper Headlight Beam Angle: One of the primary symptoms of a failing headlight level sensor is that the headlights may not adjust correctly. This could manifest as headlights pointing too high or too low, leading to poor visibility on the road or blinding oncoming drivers
• Headlights Not Leveling: If the headlight leveling system is not functioning at all, the headlights will remain in a fixed position, regardless of changes in vehicle load or terrain. This can result in inconsistent lighting performance
