What's the situation when the reverse light is on without engaging reverse gear?

[SanEllie]

The gear position and reverse light are connected by sensors and several wiring harnesses. When the transmission is shifted into reverse gear, the sensor will transmit the command to the reverse light of the tail light (whether it's an LED or an ordinary light, there will be contact), and then the reverse light will illuminate. The following is an introduction to the related content: Working principle: The reverse light switch operates as a normally open switch (normally disconnected). When reverse gear is engaged, the mechanical mechanism presses down the switch contacts, closing the circuit, causing the reverse light to turn on and the reverse gear warning sound to activate. When disengaging from reverse gear, the switch contacts spring back, and the reverse light circuit returns to an open state. The reverse light switch for tractors is generally installed on the transmission. During operation, due to the continuous high temperature of the transmission, the internal insulating rubber of the switch is prone to aging and failure, and the capacity of the switch is relatively small.
