Headlight leveling motor: replacement and selection

When and why it is necessary to replace headlight leveling motor

Specific lifetime limit is not set for the headlight leveling motor. Usually, the part is replaced because of interturn short circuit of the winding, brushes wear-out or due to mechanical damage.

The component may breakdown at strong impact as a result of a road accident. While short circuit commonly occurs due to moisture ingress or failures in the car mains.

Inability to adjust headlight angle points out a problem with the headlight adjuster. Moreover, if the leveling motor breaks down, fastening of the headlight becomes weak so the light starts to flicker.

It is necessary to adjust the headlights inclination angle after replacement of the component. This should be performed at a service station with the help of special equipment and in accordance with car operation manual.

How to select headlight leveling motor

During purchasing of this component you should take into account the fact that the headlight leveling motors do not fit all cars. Making your choice, make sure it is possible to install the exact part on your very own car.

In order to assure faultless operation of the headlight adjustment drive, give preference to manufacturers, who earned good reputation. For example, components of Hella, TYC, Valeo and Bosch are worthy paying attention.

To buy a suitable motor, you need to consider the brand, model and production year of the car. Parameters of the component, particularly, compatibility with exact bulb types, mounting location of the adjuster and others, are defined by the vehicle construction.
