A user wearable device may be implemented with a light source to provide illumination to an area of interest. In one example, the light source may be selectively operated by switches, physical displacement (e.g., movement) of the device, or other approaches. In another example, the device may be implemented as a wristwatch to display time, date, or related information to a user. In another example, the device may be implemented with appropriate processing or communication components to perform other tasks. In other embodiments, various methods of using, operating, or manufacturing such devices are provided.
