[0028] After fixation, connect the input cable and output cable of the high-mounted brake light to the two terminal blocks 62. After connection, start the second motor 81 to rotate the one-third sector gear 82. During the rotation of the one-third sector gear 82, when it contacts the gear ring 83, it will drive the gear ring 83 to rotate. The rotation of the gear ring 83 drives the pressing strip 76 to move and press against the push switch 4. After contact, the push switch 4 can be turned on to energize the high-mounted brake light. When the one-third sector gear 82 moves away from the gear ring 83, the rotating ring 73 will return to its original position under the action of the torsion spring 74. Continuously rotate the one-third sector gear 82 to make the pressing strip 76 move up and down reciprocally, continuously press the push switch 4, thereby controlling the high-mounted brake light to turn on and off. In this case, the durability test of the high-mounted brake light can be carried out;

[0029] During the up and down reciprocating movement of the pressing plate 75, the infrared emitter 10 will move up and down reciprocally. When it separates from the infrared receiver 11, the infrared receiver 11 can send a signal to the external PLC controller. In this case, the external PLC controller can control the electronic counter 3 to count. Continuously controlling the infrared emitter 10 to move up and down reciprocally can make the electronic counter 3 continuously count. When the high-mounted brake plate is damaged, the number of times of turning on and off can be accurately recorded, thereby improving the accuracy of the test.

[0030] It should be noted that the external PLC controller disclosed in the above embodiments is of the specific model Siemens S7-200. The first motor 54 and the second motor 81 can be selected as 1LE0003 three-phase asynchronous motors. The infrared emitter 10, the infrared receiver 11, and the electronic counter 3 can be freely configured according to the actual application scenario. The external PLC controller controls the first motor 54, the second motor 81, and the infrared emitter 10 to work using the methods commonly used in the prior art.
