Light bulbs are of different types: incandescent, fluorescence, light-emitting diode. Generally, the answer is heat! In common household current, AC, the current switches direction many times per second. As the incandescent bulb heats up, it twists one way and then the other. These mechanical gyrations will eventually break the filament that heats up and supplies the light. Etc.
