Rear Auto‑Leveling Height Sensor for Mazda Headlights ⚙️

Why this part is needed

This rear suspension height sensor keeps your headlight beam at the correct angle, automatically compensating for passengers, cargo, and road pitch. It protects oncoming traffic from glare, improves night visibility, and keeps the vehicle compliant with lighting regulations. Ideal for cars with HID/LED lamps and auto‑leveling systems. 🔦

How it works

A small linkage connects the sensor arm to the rear control arm. As the body height changes, the sensor sends a precise voltage signal to the headlight leveling ECU. The ECU commands the headlamp stepper motors to tilt up or down in real time, stabilizing the beam during acceleration, braking, and load changes. Simple, fast, and dependable. 🚗

What happens if it’s broken

Expect a warning light, beams pointing too high/low, flickering aim, poor night vision, and possible inspection failure. Fault codes, corroded connectors, or a seized linkage are common causes. Replace the unit and perform basic calibration with a scan tool for best results. 🔧
