Why is the reverse light always on?

[VanRichard]

The reverse light staying on continuously may be due to a faulty reverse switch. Here are the details: Influencing factors: Poor performance of the reverse radar itself: This is caused by the reverse radar control unit's own poor performance; Abnormal connection of related wiring. Introduction to reverse lights: Reverse lights are installed at the rear of the vehicle to illuminate the road behind and warn vehicles and pedestrians that the car is reversing. All reverse lights are white. Working principle of reverse lights: It is a normally open switch (normally disconnected). When the reverse gear is engaged, the mechanical mechanism presses down the switch contacts; this closes the circuit, turning on the reverse light and triggering the reverse gear warning sound. When the reverse gear is disengaged, the switch contacts spring back, and the reverse light circuit returns to the open state. Generally, the reverse light switch in a tractor is installed on the transmission and is triggered by a depression on the gear shift lever.
