Wigwag landing and taxi lights

[guccidude1]

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

I installed the non-LED version of this. Works fine.

Excellent schematic!

Just out of curiosity though, I'm not quite on the step with why one would employ a wig-wag anyway? I'd not think it a great idea at night, so is it a daytime attention catcher on landing? I'd not seen any heavies use it.....

I hope this helps:

Great attention getter anytime! With the brightness of modern LED's, I can see a good set of Wig-Wags in the pattern before I notice strobes.

The heavies have such huge landing lights that they are hard to miss, flashing or not.

The predominant reason I wanted the leading edge lights. Many times I have visited friends who were at the airport upon landing. Almost every one immediately comments on how far out they saw me - I turn then on when I contact tower or make my initial CTAF call. I also keep them on any time I'm in a high-traffic area.

I fly on the East Coast and it is not uncommon to have a good layer of haze below 6,000 ft. It sure is helpful to see other aircraft with wigwag vs strobes.

I went a slightly different way on my lights. My light switch turn both my landing and taxi lights on together. The only difference between them is the angle they are mounted within the wing. Because of this my blinker circuit is very simple:



Light Switch ON no matter where the recognition switch is = All lights on steady
Light Switch OFF/Recognition switch ON = All lights blink together
Light Switch OFF / Recognition switch OFF = All lights off

I normally leave my recognition switch ON and my light switch OFF so my lights constantly blink. If I want to keep the lights on but stop the blinking (landing at night) I just turn my light switch ON. Turn both switches OFF and the lights turn off.

What LED units are you using?
