Hello, have you placed new two lamps, both front and rear turn? Do all the lights work inside the optics both front and rear? I don't think it's a reley issue since it commands all the same. If you don't do it on the right side and you don't do it with the beacons, you would consider the problem with the lever or the wiring. However, it would not be wrong to remove the lever from its position and to bind the right side with the left to unload the piece.
