Have you traced your wires to see if one is broken? The foot switch is known to chaffe wires to the point of grounding out.

I'd check the fuses first just to eliminate that. Make sure you switch the fuse with a known good one to make sure yours is good. Pull the clip on the headlights and look at them for any corrosion too.
Have you replaced your headlights? It's really rare for both to go at the same time, but weirder things have happened.

What's the specs on your truck? I think I can find a wiring diagram that will help.
