Six years later I find the insulation on the original wiring from the switch to the lights is heat damaged. The factory wiring is just inadequate.

Our 2014 EFI had the same problem with the factory halogen lights. The light switch got hot when the headlights were on (which made for a good hand warmer during the colder winter months). Switching the halogen lights to LED headlights both solved the problem and significantly helped with night vision.
