Arnott RH-5071 Headlight Level Sensor - Front Left

Arnott RH-5071 Headlight Level Sensor

Arnott RH-5071 is a new front left headlight level sensor for vehicles equipped with air suspension height control. It measures chassis-to-road distance and sends that input to the ECU so the system can adjust air pressure as needed for consistent ride height and lighting alignment.

Compatible with select 2007-2014 Cadillac Escalade, Cadillac Escalade ESV, Chevrolet Suburban 1500, Chevrolet Tahoe, GMC Yukon, GMC Yukon XL 1500, plus 2007-2013 Cadillac Escalade EXT and Chevrolet Avalanche, this sensor is a direct-fit service part for common GM air suspension applications.

How It Works

This ride height sensor monitors the distance between the vehicle chassis and the road surface, then relays that information to the ECU. The suspension control system uses the signal to raise or lower air pressure in the air struts, helping maintain proper vehicle stance and headlight leveling. Arnott RH-5071 is a practical replacement when the original sensor is worn, corroded, or damaged.

Common Problems It Can Address

• Uneven vehicle ride height
• Headlights pointing too high or too low
• Suspension warning messages related to height sensing
• Erratic air suspension compressor cycling
• Sensor failure from road debris, water, salt, or impact damage

Installation Notes

Verify front left fitment before ordering. Inspect the connector, linkage, and mounting points for corrosion or damage during replacement. Because this is an electrical suspension sensor, confirm the connector shape, terminal style, and mounting location match the original part. Arnott RH-5071 is a new replacement part for 2007-2014 Cadillac Escalade and Escalade ESV, 2007-2014 Chevrolet Tahoe and Suburban 1500, and 2007-2014 GMC Yukon and Yukon XL 1500 front left applications, plus 2007-2013 Cadillac Escalade EXT and Chevrolet Avalanche front left applications.

Quality Assurance

Arnott supplies aftermarket suspension components with application-specific engineering for air ride systems. RH-5071 is built as a new replacement sensor for restoring accurate ride height input in supported GM vehicles.
