Lighted control panels were always a sign of the more deluxe appliances in the 1950s and into the 1960s and later for some brands. Originally, many washers and dryers were located in not so well lighted basements so the lights were a help to the user. GE even sold fluorescent light hoods that could be mounted on top of the control panels of their washers and dryers in the early mid fifties. Kitchen lighting was often poor as well so lights on ranges were used on more deluxe models.
This poor eBay seller does not know the difference between fluorescent and halogen.
Fluorescent lighting of control panels, especially when the light is within the panel, not only illuminating the appliance, but shining through the panel to backlight or shine through the labeling of the dial areas is the mark of a highly styled appliance. Add lenses that change the color of the light for different settings and you cannot ask for anything more grand. Life just does not get much better than when lighted control panels signal that wonderful appliances are awake, animated and ready to be admired and have fun with us as they perform.
