A lighting system includes a bag that has an outer wall and the outer wall has an inside surface. A lighting unit is removably attached to the bag and the lighting unit is positioned on the inside surface of the outer wall. The lighting unit is selectively actuatable to emit light downwardly in the bag with respect to the lighting unit and laterally in the bag with respect to the lighting unit. Thus, the lighting unit illuminates an interior of the bag thereby facilitating contents of the bag to be found in darkness.
