The possible reason for reversing the headlights is that the reversing lamp switch is short circuited or the reversing lamp line has a grounding fault. (2) according to the fault phenomenon and the condition that the vehicle has just repaired the transmission, the fault diagnosis method is most likely to have problems with the reversing switch. Remove the reversing light switch and find that there is no ball in the reversing switch, which causes the switch of the reversing lamp switch to be connected.
