the majority of refrigerator freezers are equipped with interior lights. These lights serve the purpose of illuminating the contents of the refrigerator and freezer compartments, making it easier for users to see what is inside, even in low-light conditions.
Having interior lights in refrigerator freezers is a common feature across different brands and models. When you open the refrigerator or freezer door, the light automatically turns on, allowing you to find items and organize your groceries more effectively. When you close the door, the light should turn off, conserving energy and extending the lifespan of the lightbulb.
That said, there may be some exceptions or specific refrigerator models designed for special purposes that might not have interior lights, but they would be relatively rare compared to those equipped with lights. To know the specific features of a particular refrigerator model, it's always best to refer to the manufacturer's specifications or consult the product documentation.
