What Causes Car Reverse Lights Not to Work?

[StJameson]

The reasons why car reverse lights do not work are: 1. The filament is broken or the bulb is burnt out due to gas leakage; 2. Poor contact of the reverse switch or disconnected wiring plug; 3. The fuse is blown. The working principle of the reverse light is: When the car is reversing, after shifting into reverse gear, the mechanical mechanism presses down the switch contacts, closing the circuit and turning on the reverse light. When the reverse gear is disengaged, the switch contacts pop up, the reverse light circuit becomes open again, and the reverse light turns off. The precautions for reversing are: 1. Adjust the interior rearview mirror properly; 2. Pay attention to both left and right side mirrors simultaneously; 3. Control the speed; 4. Stop and wait promptly when there are pedestrians or oncoming vehicles; 5. Use the reverse camera to accurately judge the distance.
