A cooler that utilizes multiple LEDs to illuminate an entire interior is disclosed herein. The LEDs are activated by a magnetic reed switch positioned between an inside liner and an outer liner of the cooler. A magnet is positioned in a lid. Removal of the magnetic field of the magnet when the lid is in an open state allows the magnetic reed switch to complete a circuit from a battery to the LEDs thereby allowing the LEDs to illuminate the entire interior chamber of the cooler.
