I apologize if this has already been discussed, as I didn't read the entire thread.

Rather than have the headlights come on with the ignition, I would probably wire some LED driving lights to the ignition. As the headlights have a lot of power draw and occupy multiple fuses, it seems like it would just be easier to wire up some low power lights to come on with the ignition. It would be easy to do and you would end up with more light at night. Good Luck
