If you wire as per the...
...AeroElectric Connection, and you get the Wig-Wag Flasher that B&C has, then:
Using three separate switches...
The Taxi Light can be switched on or off
The Landing Light can be switched on or off
The wig-wag function can be switched on or off. Note however that the wig-wag function is independent of the position of the landing or taxi light switch position, and takes precedence.
I suppose you could do all of these functions in one or two progressive toggle switch, but I chose to have three separate switches.
