OP: I have Delta headlights on my '13 JK with no problems, the problem you're describing sounds like it could be a few things:
1. Corroded wires as suggested
2. Alternator going bad
3. Battery going bad
You can have #2 and #3 tested at most auto parts stores. Which I would do to eliminate them from the equation.
As for the rest of the thread, glad to see that the writer of the Chicago Manual of Style decided to pay a visit.
