Abstract: A door lock includes a latch driving device having a thumb turn that can be switched between a locking position not permitting movement of a latch to an unlatching position when an outer handle is pivoted and an unlocking position permitting movement of the latch to unlatching position when the outer handle is pivoted. The thumb turn includes an actuator controlling a switch to a conductive state or a non-conductive state. When the thumb turn is in the locking position, the switch is in the conductive state, and a lighting element controlled by the switch generates light transmitting through the first lid. When the thumb turn is in the unlocking position, the switch is in the non-conductive state, and the lighting element does not generate light. Thus, the locking or unlocking state of the door lock can be identified by sight.
