Guys: I just installed of set of landing/taxi lights in the leading edges of my -9A, ala Duckworks design. These are 12 LED, 3550 lumens 4" x 4" units drawing 2 amps each. I am looking for a design to cause wig wagging using a flasher similar to an auto flasher or such flasher for LEDs. The amp draw should operation an auto flasher though . I envision a separate rocker switch supplying power from the exiting buss to the powered off switch breakers that operate each landing/taxi lights using the same wire runs. Since the auto flasher operates either the front or rear lights alternately on the left or right side, then I should get alternating flashes of each unit. I wonder if diodes would be needed to guarantee isolation? Anyone have any schematics that would address this idea. The simpler the better, preferably no solid state stuff. Thanks in advance for any working solutions. Dan
