Abstract
A signal output apparatus including a light-emitting element, first brightness control circuitry and second brightness control circuitry. The first brightness control circuitry is supplied with a first signal and controls a brightness of the light-emitting element according to the first signal so as to illuminate the light-emitting element at a first brightness when the first signal is ON. The second brightness control circuitry is supplied with a second signal including at least first and second states and controls the light-emitting element to be illuminated at a second brightness different from the first brightness if the second signal assumes the first state when the light-emitting element is illuminated by the first control circuitry at the first brightness according to the first signal.
