Many light fixtures have small screws holding a globe or other covering onto the fixture, covering the light bulb. In order to change the light bulb, you have to loosen the screws so you can remove the cover and replace the bulb. A small screwdriver is good for this not only because the screws themselves are small, but these can also be tight fitting places, maybe with a small amount of space between the cover and a wall or ceiling, so you won't be able to fit a larger tool in.
