Driving a car at night is quite difficult and tiring. First of all, due to the deterioration of the view of the road and the surrounding area. The eyes are tired of the constant flashes of headlights coming towards the car, precisely because the headlight range control was not installed on old cars. This device helps to optimally illuminate the road, directing the beam of light in the desired direction, while not dazzling other road users.
How the device works
The system itself and its principle of operation are the same in all vehicles. Naturally, this function is not included in the standard configuration, but it is available only in conjunction with bi-xenon or matrix headlights, as well as in cars starting from the middle class.
The adjustment system can be adjusted manually or automatically. If the device assumes manual tuning, then this is done using a regulator that is installed in the cabin on the instrument panel. With the help of rotation, the driver himself can set the lighting radius and the degree of inclination of the optics. If the adjustment is automatic, then the electronic mechanism independently determines all the parameters, depending on the position of the car and on the width of the road lane.
The mechanism of operation is very simple: sensors that record the landing of a car, a sensor that monitors the road markings and determines the radius of illumination, and the traffic controller himself, which signals the need to change.
Frequent problems
Like all systems, this one is no exception and also not perfect, because quite often various failures and malfunctions occur. Most often, problems arise with sensors, well, as in principle with all complex electronics. The sensor contains all the parameters of the vehicle's landing. In some cases, a lamp on the instrument panel comes on, which indicates a malfunction of the headlight adjustment. This is because the sensor mounting bracket is simply destroyed or displaced when the car is jolted or when the wheels are hit hard. In this case, it determines the wrong coordinates, and the correction work is disrupted.
Also, there is a possibility of damage to the contact connections. Due to the humidity of the air and temperature changes, the contacts oxidize and their permeability becomes dull. The most obvious malfunction is rather the specificity of the operation of some cars. In some cars, the adjustment angle is quite small, and the light beam is strongly lowered downward, which greatly dulls the lighting of the standard lights.
