Dome lights won't come on

I have a 1996 Jeep Grand Cherokee. I went to replace the light on the passenger side under the dashboard and as I pulled the old bulb out of the socket, the fixture sparked and the other dome lights went dead.

At first I thought I had blown a fuse, but I checked the fuse and it is okay. None of the dome lights will come on now at all. I already checked the other fuses and the fuses in the power distribution center and they are all fine.

Any ideas?

did you replace the bulb with the rest of the lights on? was the system completey off? i am asking this because my needs replacing too....

Yes. The other lights were on when I pulled the old bulb out of the socket (I had the door open).

I hope it didn't fry anything when it shorted out. I'm going to check the relay (if there even is one for the lights) when I get a chance.

I wonder if it could have caused damage to the system bus in some way...is that possible?
