A light control device comprising: a holding circuit that holds a transistor in an off state; and a timer circuit that creates time to periodically perform the detection operation when the lamp is shot. The brief description of the drawing has been amended as follows. “8...Timer circuit,” on page 10, line 15 of the specification.
9...holding circuit" will be corrected as "8...holding circuit, 9...timer circuit".
