I killed my lights!

[Purs]

Dummy me was installing some autometer gauges in my '68. I didn't have my test light and was looking for something that was hot when I turned the lights on, I touched the wire for the bulb in one of my autometer gauges to a fuse in the fuse block and got a pretty good spark. It seemed like a good idea at the time.... Anyway, now I don't have any lights at all EXCEPT my headlights. No dome, gauge, tail, or parking lights. I've checked all the fuses twice and they all look fine. What did I do, or better yet, how do I fix it? Is there a switch or fusable link somewhere that ties all the lights together except the headlights? I'm lost. Thanks in advance.
