Arnott RH-5277 Headlight Level Sensor - Rear

Rear Ride Height Sensor for Select Peugeot and Citroen

Arnott RH-5277 is a new rear ride height sensor for select Peugeot 3008, 5008, 308, and 408 models, plus the Citroen C5 Aircross. It monitors suspension position and sends the signal needed to maintain proper ride height in air suspension systems.

Key Features

• Rear-position ride height sensor for suspension level monitoring
• Black housing with a single 3-pin oval female connector and blade terminals
• New standard-grade electrical sensor
• Built for resistance to road debris, water, and salt exposure
• Lab tested for up to one million cycles
• Mounting hardware is not included

Detailed Product Information

Arnott RH-5277 is engineered as a direct replacement-style headlight level sensor / ride height sensor for vehicles that rely on suspension position feedback to keep ride height within specification. It is used on the rear position for Peugeot 3008, Peugeot 5008, Peugeot 308, Peugeot 408, and Citroen C5 Aircross applications. The sensor’s durable housing and sealed electrical design help it stand up to harsh underbody conditions while maintaining consistent signal output to the suspension control system. This part cross-references OE numbers 9806120280 and 9817443780 for the same application.

What This Sensor Helps Address

• Incorrect rear ride height readings
• Suspension warning lights related to level sensing
• Uneven vehicle stance caused by a faulty height sensor
• Delayed or inaccurate air suspension response
• Signal loss from corrosion, water intrusion, or debris damage

Installation Notes and Tips

Verify rear-position application before installation on Peugeot 3008, 5008, 308, 408, and Citroen C5 Aircross models. Inspect the connector, linkage points, and surrounding suspension components for wear or corrosion before fitting the new sensor. Because mounting hardware is not included, reuse only serviceable existing hardware or source the correct fasteners separately. Arnott recommends replacing ride height sensors in pairs when the opposite side is also worn.

Quality Assurance

Arnott RH-5277 is a new sensor built to standard-grade specifications and validated through laboratory cycle testing for long-term durability. Its construction is intended to resist common environmental exposure under the vehicle, including water, salt, and road debris.
