Abstract
A light module adapted to provide light temporarily in a confined space comprises a generally oblong and relatively thin housing that retains a bulb for providing a source of light, a power source sufficient to activate the bulb, and an electrical control circuit. The circuit includes a touch sensitive sensor for closing a circuit between the bulb and the power source to turn on the bulb, and a timer for opening the circuit to automatically turn off the bulb after it has been on for a predetermined period of time. The circuit also contains elements for requiring the sensor to be touched twice within a limited time period in order to activate the bulb.
