Some RV fridges have a switch of some sort that turns the light on all the time, using it as a little heater (for climate control or cold weather operation or some such, I can't recall precisely what at the moment).
Never heard of anything like this nor would it make any sense at all.
Called a Low Ambient Temperature switch or control (LAC or LAT). Used on some Dometic models. In low temperatures, the fresh food compartment stays at temp, but the cooling unit doesn't run enough to keep the freezer below zero, so they add heat to the fresh compartment, making the cooling unit run enough to keep the freezer cold.
