1. An image capture device for electro-optically reading indicia, comprising:

  • a) a housing bounding an interior and having an exterior front wall facing the indicia, and a light-transmissive window mounted on the exterior front wall;

    b) an imaging module located within the interior of the housing and having an array of spaced-apart sensors for detecting incident light reflected from the indicia through the window over a field of view, and an internal light source for providing background illumination; and

    c) a single pair of external light emitting diodes (LEDs) flanking the window and mounted on the exterior front wall of the housing, the LEDs being mounted in sleeves perpendicularly projecting past the window for additionally illuminating the indicia with additional illumination to generate a broad, brightly illuminated area in which the indicia is imaged.
