Hi, you can use a ON/OFF switch. Most lights can be assigned using MSFS controls menu with for example “NAV LIGHTS SET” (or similar) which will turn on NAV lights as long the button is “pressed”. This works for latch buttons.
Currently this leads to a bug so that e.g. the heading indicator knob then only has 10° steps instead of 1°. But wednesday in developer Q&A it was assured that this bug is fixed with the upcoming sim update.
And if you want further mappings, you can look here:
