I'll bet you two put the headlight bypass relays on soon after you get them back, now won't you?
It's cheap insurance against missing more events. All the old heads here will tell you that the first two things you need to do is replace the battery and bypass the ignition switch with a headlight relay kit. Taking the headlights off the ignition circuit will save the switch as well as give you bright white headlights. The resistance created by the switch causes the solder joints to become loose and fail. It more importantly caused the headlights to take on a yellowish hue and are not nearly as bright as they could be. Even upgrading the bulbs gives you no more light unless you pull power directly from the battery via relays and bypass wiring.
