Dashboard lights

[bigtee72]

My question is this: I pulled my dash apart to fix some gauges. I removed all the little light bulbs but one with my bare fingers. Now when I turn my lights on, every light bulb I touched doesn't work. The one I left alone does work. Are these bulbs like headlight bulbs? Or could I have knocked something loose. By the way it's a '74 Chevy pickup.
