Arnott BMW Headlight level sensor - 37146754921 - Rear Left RH-4266

BMW Headlight level sensor - 37146754921 - Rear Left

Keep your BMW’s adaptive lighting system performing just as it should with this Arnott Headlight Level Sensor. Attached to the suspension, this vital component constantly measures ride height and relays it to the control module—keeping your headlights automatically leveled whether you’re driving alone or fully loaded. When the factory sensor fails, you may notice beams aimed incorrectly, warning lights on the dash, or headlights stuck too high or too low. Arnott’s replacement brings everything back to spec with OE-quality design, direct-fit construction, and simple plug-and-play installation. Why Arnott? Restores lighting precision – Maintains correct beam level and clear road visibility. Exact OE fit – Installs easily without modification. Engineered for durability – Built to handle constant suspension movement and harsh conditions. Don’t put up with poor night visibility or annoying warnings. Regain safety and peace of mind with Arnott’s dependable direct-fit solution.
