Mark, this sounds like someone connected an additional dash lamp to your existing dash lamp circuit, using no plunger switch.
Noooooooooo.... The power comes from your clock power, which is always on. The glovebox door (plunger) switch is supposed to work just like a door switch, it grounds the lamp when you open the door.
This light should never dim with the dash lights. You can use a standard #57 bulb. - Dave
