@Heywooood, I had the taxi and landing lights set to TOGGLE LAND LIGHTS and TOGGLE TAXI LIGHTS through MSFS. When I changed the Landing Lights to FSUIPC it quit going ONOFFONOFF. The taxi lights continued to behave in that way. So, it seems to be something via MSFS. Since MSFS doesn't allow a setting change when the switch is returned to OFF, I had to use the TOGGLE function. With FSUIPC I was able to set the landing lights to ON and then OFF on release, like a real world switch would work.
