A high-intensity LED is integrated into a wireless phone device to provide an extremely convenient flashlight functionality at the ready for a user in possession of their wireless phone, particularly useful in emergency situations. When an emergency or other need emerges suddenly and while the user is otherwise unable to obtain a conventional flashlight, use of a wireless phone flashlight provides a useful source of light for both comfort and safety of the user of the wireless phone device. In another aspect of the invention, the wireless phone flashlight is a peripheral device connected to a digital port of the wireless phone. Alternatively, the flashlight is formed in such a shape as to fit into an external memory card slot of a target wireless phone (e.g., in the shape of a SmartCard), drawing power and even control from the wireless phone through the connector otherwise intended for a memory card. |
