专用汽车与乘用车、卡车的区别在于通常会加装各种不同的专用装置,而这些装置往往会影响基型车上各种灯具的作用,必须配备必要的灯具以满足作业和运输的要求。因此,专用汽车比乘用车、卡车等更喜欢“装灯”。本文从典型专用汽车上加装的照明灯、标志灯、指示灯、警示灯和装饰灯等几个方面详细阐述了欧美专用汽车“装灯”的目的和原则。 The difference between SPVs and passenger cars and trucks is that they usually incorporate various special devices that often affect the function of various types of lamps on the base vehicle and must be equipped with the necessary lamps to meet the requirements of operation and transportation . Therefore, special purpose vehicles prefer “loading lights” to passenger cars and trucks. This article elaborates the purpose and principle of the “special lights” in Europe and the United States from several aspects such as lighting, sign lights, indicating lights, warning lights and decorative lights installed on typical special purpose vehicles.
