This sensor measures the level position of the vehicle to adjust the headlight beams accordingly. This ensures that the headlight beams are directed where the driver needs them to be, and not too high or low for proper night visibility. The sensors most commonly fail due to accidents or debris and can also draw incorrect readings if the control arms they are attached to have become damaged. By simply replacing these sensors, you can get your headlight leveling system back in top shape.

These sensors do not include the couplings rods that attach them to the vehicle's suspension.
