Headlight Issues
a hi watt bulb can burn the ign switch contacts- if that is the problem than you need to think about replacing the switch before you are 400 miles from home ( $$$).
or a handy Fella could bypass the ignition switch wiring and install other switches for the ign and lights.
you could also look at the fuse box- it could be corroded.
below is a pic of my fuse cleaning kit...dirty on left ( about 4 years old) and cleaned on right. scotchbrite pad to clean and dielectric grease for the legs.
I also cleaned the fuse sockets with a fine abrasive

this could be the tedious task of going through the wiring harness from fuse box to load.
I don't have a wiring diagram for your year- my 09 has a relay for the headlamp and spots- if yours has a relay, I'd check that as well as the connections in and out of it.
On the 09, this relay is on the fuse box and is same spec as the other relays and can be swapped to test.
you fuse panel may be labelled as to relay function.
