A delay circuit comprising two leads adapted to be connected across a light switch for delaying the turn off of a light bulb after the switch has been turned off. A silicon controlled rectifier (SCR) is connected across the two leads for applying power to the bulb when the SCR is on. An integrated circuit including an oscillator and a counter provides an output to the gate of the SCR for a predetermined time period following the opening of the switch for enabling the SCR to turn on.

A delay circuit comprising two leads adapted to be connected across a light switch for delaying the turn off of a light bulb after the switch has been turned off. A silicon controlled rectifier (SCR) is connected across the two leads for applying power to the bulb when the SCR is on. A capacitor is connected to one of the leads for controlling circuitry coupled to the gate of the SCR for turning the SCR on for a given time period following the opening of the switch. A quick discharge circuit is provided for rapidly discharging the capacitor when the switch is closed.
