Front Headlight Level Sensor for Subaru 🚗

This ride height sensor keeps your headlamps correctly aimed in all loads and road conditions. It measures the front suspension angle and sends precise data to the leveling ECU so the headlight motors adjust beam height automatically. Result: safer night driving, no glare, and factory-spec visibility. It’s an OE-style auto leveling sensor designed for reliable, plug-and-play performance.

Why this part is needed

Correct ride height data keeps self-leveling headlights legal and sharp. It prevents dazzling other drivers and avoids a dim, short beam. It also supports stability systems that expect accurate chassis height input. Replacing a tired sensor restores proper light aim and compliance. 💡

How it works

A short link rod connects the control arm to a sealed potentiometer/Hall element. As the suspension moves, the sensor outputs a voltage sweep; the ECU translates it into motor steps, raising or lowering the beam in real time. Weather-sealed housing fights water and road salt.

What happens if it’s broken

Symptoms: auto-level warning, VDC/ESP light, headlamps too high/low or “bouncing,” and DTCs for height sensor range/performance. Corroded connectors or a seized arm are common. Ignoring it risks poor night vision, inspection failure, and lamp motor strain. Replace, clear codes, and run calibration. 🛠️
