    Bulb means:

    1. almost round, thick, underground stern, sending roots downwards and leaves upwards, of such plants as the lily, onion, tulip.

    2. sth like a bulb in shape, esp an electric lamp or swollen end of a glass tube, eg in a thermometer

    Therefore, "bulb" can be used without "light"

    For example, the bulb of a thermometer, or the bulb of an onion.
