Obviously either some connection came loose or but bulb(s) broke. The bulbs are easy to test. If they're okay, the fuse is the next thing, since they can get shaken loose. After that, it's just a matter of tracing through the wiring. I'd start by checking the ground at the headlight itself. There should be no voltage at the ground (common pin) on the headlamp when the switch is on. If there's voltage there, fix the ground wire. After that, tracing through wiring is most efficient if you start somewhere in the middle (with a roughly equal number of parts and connectors on each side of it), find out which half the problem is in, then check near the middle of that half, and so on.
