In order to avoid erroneous manipulation of alarm ON/OFF and sleep buttons, on a clock radio type alarm, a night light is provided to illuminate at least these two buttons when the alarm ON/OFF button is set to it's ON position. An illumination level control is provided which allows the brightness of the night light to be selective controlled or turned off irrespective of the alarm button being set to its ON position. The night light preferably includes two readily replaceable bulbs which are circuited in such a manner that when one becomes defective, the other can be still be energized.
