My memory is hazy but I believe there were two circuit breakers associated with the leading edge devices, a "leading edge valves" and a "LEFUS". I never saw it done but pulling one would allow you to extend the flaps without the LEDs. One rumor was that they were trying out the idea and didn't understand the system that well and pulled the wrong CB.
