There is no reversing lamp on the Daewoo Nexia

If the reversing lamp on the Necsiah stopped turning on when the rear gear was switched on, the problem is most likely in the switch, in the people called the "frog". To replace it, you must first disable the electrical outlet. To spin the frog itself, you will need a 19-track head. It is not difficult to determine the "frogs": if both lamps are not lit simultaneously, the problem is probably not in the lamps.
