Driving at night must be open, the tractor headlight, headlight luminescence intensity and nearlight irradiation position to the safety of driving at night can play a vital role. When the irradiation direction is not normal, the beam from the ground distance is not appropriate, should adjust the headlamp up and down adjustment screw, so that it can achieve the ideal lighting state. But in practice, headlight problems are often ignored by drivers. The following enumerates the improper operation phenomenon in the installation and use of some headlights, which should be avoided diligently. Tractor headlamps light alone when a light bulb is damaged, should be replaced immediately, if still using another bulb make use only, can make the tractor when driving at night in front of the illuminance is greatly reduced, and the light deflection a side, in the rainy night, and the rural roads due to the line of sight is not clear, the road is narrow, it is easy to cause rollover accident. In addition, non-motorized drivers and pedestrians cannot tell whether the beam is coming from the left or right side of the tractor, and do not know which direction to avoid. Lamp installation position is too high when the filament burns out and the entire component needs to be replaced, it should be replaced immediately. Some drivers save money by welding a higher bracket above the nose and switching to detachable or semi-detachable headlights. This makes the headlight position greatly elevated, many lamps and lanterns position almost equal height with the driver's eyes, in the night when the headlight driving, the driver's line of sight always has a dark shadow (namely the rear of the lamp shell) in front of the eyes, will seriously hinder the driver's observation of the road ahead, but also easy to make eye fatigue. The installation position of lamps is too low. Many small four-wheel and walking tractors refitted headlights on the frame. Because of the low power and short range of the bulb on the tractor, the light beam cannot illuminate the traffic signs in the distance ahead of the road. When the tractor opens close, because the lamp position is too low, the main light still illuminates the roadside traffic sign, the driver can not distinguish the road sign, such as in the case of sharp turn, steep slope and other dangerous sections, prone to traffic accidents. In addition, because the lamp position is too low, small ups and downs on the road will also cast a long dark shadow, affecting the driver's ability to judge the road. Improper adjustment of the headlight axis direction when the driver installs the lamp bracket, if the bracket is not corrected or adjusted improperly, it will cause the headlight axis can not keep basically parallel to the road surface, which affects the driver's observation of the road. When using the nearlight, the beam of the nearlight is not inclined to the lower right side of the front of the car according to the requirements, but to the front, which will make the oncoming driver dizzy. Astigmatism glass position installed oblique or inverted astigmatism glass surface has many pieces of lens and prism shaped composite corrugated, it can reflect the mirror light for directional refraction and scattering, so that the headlamp to the horizontal plane and the right side of the lower part of a certain light distribution of light beam. Some drivers do not pay attention to the direction when replacing the astigmatism glass, so that the direction of light refraction can not well illuminate the road surface. In order to ensure that the installation is correct, the word is generally cast on the astigmatism glass, and the word must be placed correctly when replaced.
In the process of using and maintaining the tractor, in order to ensure the distribution of headlight to meet the needs of driving, it is required that the power supply is sufficient, the lamps and lanterns are intact, and the installation is correct, otherwise it will directly affect the driver's accurate observation and judgment of road signs and pavement. In addition, in order to make the headlight beam can achieve satisfactory results, in addition to ensuring the correct installation of lamps, should also pay attention to the overall situation of the locomotive, as far as possible to reduce the locomotive jitters.
