So if you are happy to have a extra "manual" overide switch as well, then surely you would wire the trigger through IGN, and now use the manual overide switch to simply bypass the whole relay "alltogether", this would effectivly return the whole system back to factory while the switch is off. (then you can have no lights in the day etc)
This way you dont have any of the downside's (such as the one you mentioned above)
You could also make it, so every time you re-start the car, it defaults back to "auto headlights" ,so you would have to manually deactivate the function off every time, then at least you cant forget to turn it on.
