A device which can be set to start a light flashing unattended at a predetermined time. The device includes a light and a battery, together with a small electronic clock. The clock has a display for displaying a time, a memory for holding a settable alarm time, and alarm output terminals for outputting a signal at a pre-established time stored in the memory. An electronic control circuit receives the signal from the clock at the pre-established time, and causes the light to begin flashing at that time. In the embodiment shown here, the control circuit flashes the light for a predetermined time, and then turns the light off. In this embodiment the device includes a casing, and a switch mounted in the casing and electrically connected between the battery and the light. By this switch, the light can be turned on and off in a manner generally conventional for a flashlight. The casing includes a telescopic slider, and a lens, mounted so that the lens is exposed when the casing is telescoped to be longer, and not exposed when the casing is telescoped to be shorter. A second switch is mounted to the telescopic slider. That second switch is electrically connected to the electronic control circuit so that, if the light is flashing, closing the telescopic slider stops the flashing of the light before the end of the predetermined time.
