Rear Left Headlight Level Sensor GRP Housing for Seat Leon 2012-2020 Model Year Range
The Seat Leon Rear Left Headlight Level Sensor with a robust GRP housing is a genuine‑style replacement designed to restore your vehicle’s automatic headlight leveling. Built for Seat Leon models from 2012–2020 and Skoda Octavia III from 2012–2020, this sensor ensures headlights stay correctly aimed as load changes, improving nighttime visibility and reducing glare for oncoming drivers. The GRP (Glass Fibre Reinforced Plastic) housing combines light weight with durability, resisting wear and environmental factors for reliable performance over time.
Key features include a 4‑pin connector, D‑shape connection, and OEM‑standard specifications, making it a precise, plug‑and‑play replacement for the original part. The sensor operates via magnetic induction and is intended for vehicles equipped with automatic headlight leveling, including those with air suspension systems. The package arrives with everything needed for installation: the sensor itself along with the holder, coupling rod, and holding frame.
