The landing lights already on the wings were the old 10 amp/light style. Duckworks, the maker, has a new lower amp version that reduces the amps to 4.5. They offer an upgrade kit. The kit is well designed and very good instructions made the change over easy. The lights are located on each wing, on the leading edge, just inboard of the wing tip. There is removable lens on the leading edge that is removed to access the landing light and mounting bracket.
