When it reaches the set position, the lifting component works to drive the structure to descend, and the test plug 39 is combined with the headlight body 18 for testing. The testing method can be achieved by inserting the test plug 39 into the interface of the headlight body 18, measuring the working state of the headlight by supplying power, and detecting its working parameters, such as power resistance, etc., which will not be elaborated here.
