The automatic concrete loading mixer is equipped with daily running lights. The driver must first understand the working principle of these devices. For example, some daily running lights cannot be turned on before the start-up of the automatic concrete feeding mixer; and for some daily running light systems, if the parking brake of the automatic concrete feeding mixer has not been cancelled, even if the engine has been started, the daily running lights still can not work normally.
如果混凝土自动上料搅拌车的前大灯损坏，通常采用类似的灯具进行更换。有些混凝土自动上料搅拌车装备了高强度放电请大灯HID，该设备通过其预先设计的电子系统产生的高压电弧生成高密度光源。注意，普通的石英-卤素灯泡不能在此应用。另外，还要检查混凝土自动上料搅拌车前大灯是否有裂纹，因为虽然表面裂纹并不会影响前大灯的照明性能，但是湿气会沿着裂缝渗入灯具内，这势必将会降低灯泡的使用寿命。
If the headlamp of the automatic concrete loading mixer is damaged, it is usually replaced by a similar lamp. Some automatic concrete charging mixers are equipped with high-intensity discharge headlight hid, which generates high-density light source through high-voltage arc generated by its pre-designed electronic system. Note that ordinary quartz halogen bulbs cannot be used here. In addition, it is also necessary to check whether there are cracks in the headlamp of the automatic concrete feeding mixer, because although the surface crack will not affect the lighting performance of the headlamp, moisture will seep into the lamp along the crack, which will inevitably reduce the service life of the bulb.
混凝土自动上料搅拌车前大灯关照方向的校准也应列入维护项目清单中，因为为了确保驾驶者行车的，混凝土自动上料搅拌车必须能够为行驶混凝土自动上料搅拌车提供良好的前向照明。
The alignment of the headlamp direction of the automatic concrete feeding mixer should also be included in the list of maintenance items, because in order to ensure the safety of the driver, the automatic concrete loading mixer must be able to provide good forward lighting for driving the automatic concrete feeding mixer.
抓住关键之余，也切不可忘记检验其它灯系，如混凝土自动上料搅拌车转向灯、车牌照明灯，示宽灯，驻车灯、倒车灯以及刹车灯等。另外，许多混凝土自动上料搅拌车还将雾灯作为标准装备或流行的选装件，雾灯一般安装在较低的位置，因此极易受到石块的损伤，在对其进行维护时，除了检查照明系统本身外，混凝土自动上料搅拌车的车灯的裂纹也不应该不忽略。
In addition to grasping the key points, we should not forget to inspect other light systems, such as turning light, license plate light, width indicator light, parking light, reversing light and brake light of automatic concrete feeding mixer. In addition, many automatic concrete loading mixer also use fog lamp as standard equipment or popular option. Fog lamp is generally installed at a lower position, so it is vulnerable to damage by stones. In the maintenance of the fog lamp, in addition to checking the lighting system itself, cracks in the lamp of automatic concrete feeding mixer should not be ignored.
