A flashlight has a housing and a circuit mounted in the housing. The circuit includes a light, batteries for powering the light, and a switch for opening and closing the circuit. A switch control accessible from outside the housing can be pressed to close the switch and turn the light on momentarily or rotated to close or open the switch and turn the light on or off stably. The housing has a straight portion that houses batteries and a curved portion that houses a light. A key holder is attached to the straight portion by a flexible link and has a loop for holding keys. The key holder is constructed so that keys can be easily inserted in and removed from the loop and are held securely when inserted. The apparatus is well suited for use under poor ambient illumination to find a keyhole and insert a key properly for operation of a lock.
