I have the Aerosun VX combined landing and taxi lights.
There are 5 wires on each light. 2 of the wires are for their internal wigwag function which I did not use.
I ran the power wire from each landing light to a separate power pin on my VPX. Having 2 power pins for the landing lights allows using the wigwag function in the VPX.
I ran the two taxi light power wires to a single VPX power pin
3 VPX power pins total.
Each light was grounded separately at each of the wingtips.
I set up two switches in the VPX, one for the landing light power and one for taxi light power. The landing light switch setup turns on the power for both landing light power pins.
If you read some of the Bob Knuckles AeroElectric Connection files, you can find a way to use only one physical switch to control both taxi and landing lights. I have a 3 way switch where down is off, middle is taxi, and up is both landing and taxi.
The VPX is programmed to start wigwag at 100 knots.
