*It is critical to replace all of the lights in the 3-door cooler even if there is only 1 or 2 lights not working. Replacing all 4 lights and the driver will give the 3-door case a brand-new lighting system. The PureView RDL Cooler Door Lights are the approved Costco replacement for POS Cooler and Freezer Cases.
