Methods are disclosed for triggering a source of visible light in connection with a data reader in response to a sensed proximity of an item. In one configuration, a data reader includes a imaging reader, such as a CMOS imager, that is sensitive to both infrared illumination and visible light. The imaging reader may be operable to read a symbol, such as a barcode or other optical code, via reflected infrared illumination, reflected visible light, or both. When characteristics of reflected illumination received by the imaging reader indicate that presence or movement of an item in the visible scan zone, the visible light source may be triggered to illuminate the item and thereby facilitate reading of the symbol using the same imagine reader as is used to sense the presence of the item. The visible light source may also be triggered to provide visual feedback.
