In Bulb Mode, a light bulb will light up when you press the shutter release. Then you can see what you are doing.

Ok, jokes aside, bulb mode is a mode where the shutter will open when you press the shutter release, and close when you release it. So it allows for very long exposures, in your e.g, 60s maximum. In SLRs, bulb mode allows for unlimited exposure time as long as the battery can support, or for the case of mechanical SLRs, it's really unlimited length.
Hope this helps.
